Bobbi Kristina Brown, the 21-year-old daughter of the late Whitney Houston, was found face-down and unresponsive in a bathtub Saturday morning and was rushed to the hospital, Roswell authorities said. 
 
 TMZ is reporting that sources close to the family say she’s been place in a medically induced coma to address swelling. An AJC reporter was told to leave hospital property Saturday and no hospital representatives were available for official comment. 
 
 “She is still alive and breathing and other than that I do not know her condition at this time,” Roswell Police Department public information officer Lisa Holland said during a Saturday afternoon news conference. “Investigators are on the scene at the hospital and the house.” 
 
 At a later news conference Holland said she had no information regarding any sort of medications being found at the home, and said she could not comment regarding Brown’s condition due to medical privacy laws. She didn’t know how long Brown had been in the bathtub before being being discovered, and said there was no sign of struggle.

 UPDATE: Celebs post prayers, support for Bobbi Kristina 
 
 Roswell police and fire/rescue personnel arrived at 10:25 a.m. at the home in the Ellard subdivision off Holcomb Bridge Road, after Brown’s husband Nick Gordon and a friend found her in the tub, unresponsive. She was taken to North Fulton Hospital, and police are on the scene investigating. 
 
 “As a procedure, they’re getting a search warrant on the house,” Holland said. “They will go through and just make sure everything is covered.” 
 
 She didn’t know if Brown’s father, Bobby Brown, had arrived at the hospital but did say there were four people along with Bobbi Kristina in the house (including her husband) at the time of the incident. 
 
 On Jan. 23 police were called to the home regarding a “disturbance” but when police arrived no one was home at the time, Holland said. 
 
 Houston died at age 48 in February 2012. She was discovered in a bathtub at the Beverly Hills hotel room. The official cause of Houston’s death was drowning and the effects of atherosclerotic heart disease and cocaine use, according to the Los Angeles coroner’s office. Toxicology results showed Houston had marijuana, Xanax, the muscle relaxant Flexeril, and the allergy medication Benadryl in her system. 
 
 Holland noted the sad parallel between the two cases: “We wish the family well and our thoughts and prayers are with this family.” 
 
 Bobbi Kristina, who with several members of her family starred in a short-lived Lifetime reality show, has been in the news sporadically since her mother’s death and has frequently taken to social media to respond to various reports. In July 2014, she vented via Twitter, furious that someone posted a photo purporting to be her, smoking marijuana. 
 
 “I’ve never posted any photo of me doing anything! This is someone trying to tarnish and make a horrible name for MYSELF,” Bobbi Kristina posted. “People are insane.” 
 
 Krissy, as she is known in her family, had previously lashed out at critics who commented about what some thought was her emaciated frame. 
 
 “Think I care?” she posted along with a one-finger salute. 
 
 In happier news, about a year ago, Krissy announced via social media that she and Gordon had wed, changing her Twitter bio to”Wife of @ndgordon4life” and using the hashtag#HappilyMarried.” She’d announced their engagement on the Lifetime show, “Houstons On Our Own.” 
 
 Krissy and Nick have made assorted headlines in metro Atlanta. She was cited after a car wreck and he was arrested on speeding charges (in two separate incidents). Authorities had also responded to a noise complaint and found evidence of another auto incident. 
 
 But more recently, Bobbi Kristina indicated she was moving forward in a positive direction, hinting that she was pursuing a music career modeled after her mom and dad, singer Bobby Brown. 
 
 “I hope you all understand how much you guys mean to us,” Bobbi Kristina posted in a happier time last summer. “Thank you thank you thank you! Promise to release some thangs for your enjoyment!” 
 
 She also said her mother was an inspiration. 
 
 “No matter what, I will continue to stand my ground as a young woman,” she posted. “One thing you CAN depend on is my mother taught me well.”

 A source close to the investigation says injuries to Bobbi Kristina’s face and mouth have Roswell police concerned and investigating further. 
 
 Police are also looking into suspected drugs found in the home in the 9000 block of Riverbend Manor in Roswell. 
 
 Brown was found unconscious in a bathtub of that home, face down in the water, according to police. She has been in a medically induced coma since Jan 31. 
 
 No charges have been issued in the case. Channel 2's Mark Winne worked all weekend to obtain a search warrant affidavit or search warrant return but is getting conflicting information about whether those records have been sealed from public view. He also tried to obtain a search warrant for medical records. 
 
 Channel 2's Dave Huddleston spotted her father, Bobby Brown, and grandmother, Cissy Houston, arriving at Emory University Hospital on Monday. 
 
 Brown is being treated in the neuro intensive care unit at the hospital. 
 
 Riverdale spokesman Corey Punzi says Bobby Brown helped christen the Riverdale Amphitheatre so the city is showing their support. 
 
 "We want to bring the family together as one collective unit and just provide positive energy in the direction of Bobbi Kristina Brown," Punzi said. 
 
 Monday night, fans, church members and community leaders gathered to pray for Brown's recovery. 
 
 Channel 2 Action News attended a public vigil for her in Riverdale, where family members said she is doing better and asked for continued prayers. 
 
 "Tonight meant a lot to see the family, to see supporters come out in prayer for my cousins, it means a lot to the family," Bobbi Kristina Brown's cousin Shayne Brown said. 
 
 He asked that everyone continue to pray for his cousin.

 While her prognosis still isn’t good, the new test results have halted talks about pulling the plug on Brown, who is in a medically induced coma in a Georgia hospital, family sources said Monday. 
 
 Whitney’s daughter was able to move her eyes, and the amount of oxygen going to her brain increased significantly Monday, TMZ reported. 
 
 Doctors fear she might have suffered permanent injuries after going without oxygen for two to four minutes on Saturday. 
 
 Brown, 21, was found unconscious in her bathtub in an eerie reminder of her mom’s death nearly three years ago. 
 
 “Bobbi Kristina is fighting for her life and is surrounded by immediate family,” loved ones said in a prepared statement on Monday. “As her father [singer Bobby Brown] already stated, we are asking you to honor our request for privacy during this difficult time. Thank you for your prayers, well wishes, and we greatly appreciate your continued support.” 
 
 Missy Elliott, who performed at the Super Bowl on Sunday night, said she’s praying for Brown. 
 
 “Bobbi is like a little sister to me,” she told The Insider. “One thing that her mother said to me before she passed away was to make sure Bobbi Kristina was straight, so my prayers for healing [are] that she comes out and be around people that love her.” 
 
 Police, while still investigating, have said that no illegal drugs were found in Brown’s home. 
 
 Additional reporting by David K. Li ||||| Things aren’t looking good for Bobbi Kristina Brown. 
 
 
 
 “It’s now a matter of when the family wants to let go and accept that she’s pretty much not going to make it,” a source closely connected to the situation told FOX411, adding that doctors have expressed that there is little they can do. “They’ve left it up to the family as to how long they want to keep her alive.” 
 
 
 
 Earlier this week, reports emerged that the situation involving the daughter of Whitney Houston and Bobby Brown was particularly weak and her brain function was “alarming low” after being placed in a medically-induced coma. 
 
 
 
 However, we’re told that Bobby Brown is remaining hopeful and rallying others to stay uplifted – refusing to acknowledge the worst-case scenario. 
 
 
 
 On that note, a source connected to the Houston family has said that the 21 year old’s condition has actually improved somewhat, with things looking better than they were earlier this week. 
 
 
 
 Christopher Brown of Brown & Rosen LLC, legal counsel for Bobby Brown, told FOX411 late Tuesday that they are currently investigating the events that led to the hospitalization of Bobbi Kristina, adding that contrary to media reports, the young performer has never been married to Nick Gordon. 
 
 
 
 “We continue to request privacy in this matter. Please allow for our family to deal with this matter and give Bobbi Kristina the love and support she needs at this time,” Bobby Brown added in a statement. 
 
 
 
 A man previously arrested on drug distribution charges was the friend who, along with Gordon, discovered Bobbi Kristina Brown face down in a bathtub, unresponsive on Saturday. Police officials said that Gordon immediately began administering CPR before paramedics arrived. 
 
 
 
 According to MyFoxAtlanta, Maxwell Byron Lomas is named in an incident report as one of the people police encountered when they responded to a drowning. 
 
 
 
 Citing Fulton County Jail records, MyFoxAtlanta revealed Lomas was arrested as recently as Jan. 14 and charged with possession of marijuana with intent to distribute, possession of Alprazolam and possession of firearm or knife during commission of or attempt to commit certain felonies. 
 
 
 
 Brown was rushed to a hospital in Northern Atlanta on Saturday. TMZ has reported that she has since been relocated to another hospital, although the details as to when and why remain unclear. 
 
 
 
 The incident bears an eerie resemblance to the death of Brown’s mother almost three years ago in Beverly Hills. Houston, then 48, who had struggled for years with drug addiction, was found dead in a bathtub at the Beverly Hilton Hotel. The official cause of death was labeled accidental drowning, with heart disease and cocaine use deemed contributing factors. 
 
 
 
 “Bobbi Kristina is fighting for her life and is surrounded by immediate family,” a family statement said Monday. “We are asking you to honor our request for privacy during this difficult time.” 
 
 
 
 A representative for Bobbi Kristina did not immediately respond to a request for comment. 
 
 
 
 Just last Thursday, the 21-year-old tweeted her excitement about continuing in her late mother’s footsteps, and her excitement to “get this career started already.” A well-placed insider later told FOX411 that the budding performer was planning to record a tribute album to her mom with her father this year.

 Attorney Christopher Brown also said Tuesday that the 21-year-old daughter of singers Whitney Houston and Bobby Brown "is not and has never been married to Nick Gordon," contrary to some reports. 
 
 Bobbi Kristina Brown was found facedown in a bathtub over the weekend. Her family has been tight-lipped about her condition, but her R&B singer father issued a statement through his lawyer Tuesday night. 
 
 "We continue to request privacy in this matter. Please allow for our family to deal with this matter and give Bobbi Kristina the love and support she needs at this time," Bobby Brown said in the statement. 
 
 After she was discovered unresponsive in her home in the Atlanta suburb of Roswell, Brown was rushed to a hospital, where doctors placed her in a medically induced coma. As of late Monday, she remained on a ventilator in the intensive care unit, a source close to the family said. 
 
 On Tuesday, she was moved to Atlanta's Emory University Hospital, sources close to the family said. 
 
 The status of her brain function won't be known until sedatives are reduced, the source told CNN. 
 
 "Bobbi Kristina is fighting for her life and is surrounded by immediate family. As her father already stated, we are asking you to honor our request for privacy during this difficult time," the Houston family said, thanking her supporters. 
 
 The source close to the family told CNN that Brown's eyes opened and closed a few times Monday, but that doctors told family members not to read too much into that movement. 
 
 Doctors were trying to reduce the sedatives to check Brown's brain function but decided to keep her in the coma for now, the source said. 
 
 The source added that Brown had seizures Monday. 
 
 It was not immediately clear what medical significance these reported events have in Brown's case. 
 
 She "was not breathing" when Nick Gordon and a friend, who's been identified as Maxwell Lomas, found her Saturday morning inside her townhouse in the Atlanta suburb. 
 
 They called 911 and performed CPR until emergency crews arrived and took over, police spokeswoman Lisa Holland said. 
 
 The spokeswoman said when Brown was found, she was "unresponsive, meaning not breathing, no heartbeat." 
 
 In scanner traffic, emergency services could be heard describing an "ECHO-level response" -- urgent and life-threatening -- with "possible cardiac arrest." 
 
 "Twenty-one-year-old female in the bathtub, facedown. PD's (police department's) en route." 
 
 On Monday, a source close to the family told CNN that Brown was in "really bad shape." 
 
 Everyone is "hoping for the best, preparing for the worst" and "praying for a miracle," the source said. 
 
 Police call it a medical incident 
 
 Nobody knows what caused Brown's unresponsiveness, Holland said, but police consider it a medical incident at this time. She said investigators had found nothing to indicate it was drug- or alcohol-related. The incident report referenced a drowning. 
 
 Police had been to Brown's residence recently. Somebody reported a fight there on January 23, but nobody answered the door and officers found no evidence of an altercation, Holland said. 
 
 Bobbi Kristina Brown and Nick Gordon attend the GRAMMY Gift Lounge during the 56th Grammy Awards on January 25, 2014, in Los Angeles. 
 
 Almost three years ago, Whitney Houston was found dead in a bathtub at the Beverly Hilton hotel near Los Angeles, hours before she was to attend a pre-Grammy Awards party. 
 
 A coroner ruled her February 11, 2012, death an accidental drowning , with heart disease and cocaine use listed as contributing factors. 
 
 Brown is her only child. 
 
 "She encourages me and inspires me," Houston once said of her daughter. "When I look at her eyes and I see myself, I go, 'OK. I can do this. I can do this.' " 
 
 Daughter of acclaimed singer, R&B standout 
 
 Brown was born in 1993 during Houston's marriage to R&B singer Bobby Brown, which ended in divorce in 2007. 
 
 The daughter of music royalty became a public figure during the mid-2000s reality show "Being Bobby Brown," in which she frequently appeared alongside her parents and often had a front-row seat to their marital fireworks. 
 
 Mother and daughter performed together on national TV in 2009, when the two sang "My Love Is Your Love" in Central Park on ABC's "Good Morning America." 
 
 Given the pair's close relationship, it's no surprise that Houston's death was a major blow. 
 
 Days after her mother's body was found, a grieving Bobbi Kristina -- then 18 -- was taken to Cedars-Sinai Medical Center because she was "overwhelmed," family friend Kim Burrell said. 
 
 "She loves hard," Burrell said then of Bobbi Kristina. "She's going to be OK, and we're going to see to it." 
 
 Leaning toward show business 
 
 After Houston's death, Bobbi Kristina talked of pursuing a career in acting and music, just like her mother. 
 
 In 2012, she reportedly lobbied for a role in a planned biopic of her mother's life. Lifetime's "Whitney," which was directed by actress Angela Bassett, debuted in January 2015, but the Houston family was not involved. 
 
 Brown did make her acting debut in 2012 on Tyler Perry's show "For Better or Worse." Her performance in the small role won praise from Perry. 
 
 "She did a fantastic job," he said at the time. "And that kid has such a future. She's such an actor. " 
 
 Even before her mother's death, videos of Brown singing surfaced on YouTube and were quickly criticized by fans who felt her talent did not live up to Houston's. 
 
 The caption read: "This picture may be inappropriate but I want to make a connection with you all. Don't worry this picture isn't recent just hear me out. Do you know what I feel? I feel strange I can't feel any pain anymore. I don't take any drugs as of recently. Things just happened. But then there is some situation that force me to do things and the impact I'll feel pain. I did and I do. I was hurt." 
 
 Brown later denied that she posted the photo and tweeted that it was done by someone attempting to tarnish her image. 
 
 I've never posted any photo of me doing anything ! This is someone trying to tarnish and make a horrible name for MYSELf. People are insane — Bobbi Kristina H.G. (@REALbkBrown) July 15, 2014 
 
 Relationship with a man taken in by Houston 
 
 Brown appeared on episodes of Lifetime's brief reality show "The Houstons: On Our Own," which followed her life after Houston's death. 
 
 One of the show's story lines revolved around Brown's relationship with Nick Gordon, who had lived with Houston and her daughter since he was 12 years old. 
 
 Brown reportedly got engaged to Gordon , and in January 2014, she tweeted out a picture of wedding rings along with the words, #HappilyMarried• SO#Inlove." However, Bobby Brown attorney Christopher Brown said Bobbi Kristina was never married to Gordon. 
 
 "(Houston) made me promise several times to look after Krissy ... and, Mom, I will never, ever, ever break that promise," Gordon told the entertainment show "Extra " afterward, saying Houston "just treated me like she gave birth to me." 
 
 Bobbi Kristina Brown is seen in a photo she posted to Instagram around 2 a.m. ET on Saturday, January 31. 
 
 It was unclear whether Gordon and Lomas came into the home Saturday morning to find Brown in the bathtub or if they had been in another part of the house overnight, said Holland, the police spokeswoman. 
 
 The whereabouts of another man who was in the house when Brown was found, Maxwell Lomas, are also unclear. But in response to several media outlets reporting Lomas' lengthy rap sheet, attorney Philip Holloway issued a statement Tuesday saying his client is a cooperative witness and Lomas' most recent arrest in January has nothing to do with Brown's hospitalization. 
 
 Holloway also told CNN Wednesday that his client was the one who actually found Brown and called 911. Holloway's comments came after he met with Roswell police for two hours; his client was not at the meeting, he said. 
 
 On January 15, Lomas was booked on charges of possession of marijuana with intent to distribute, possession of alprazolam (aka Xanax, an anti-anxiety drug) and possession of a firearm or knife during the commission of or the attempt to commit a felony, according to Fulton County Sheriff's Office spokeswoman Tracy Flanagan. 
 
 CNN has also learned from Fulton and Dawson county authorities that Lomas was arrested at least three times in 2011 and 2012 and charged with a host of crimes, including battery and alcohol, weapons, drug and probation violations. Holloway did not mention the previous arrests in his statement. 
 
 "Mr. Lomas' widely reported recent arrest is completely unrelated to the incidents that occurred at Ms. Brown's residence and there is absolutely no relationship between the events. He has pleaded not guilty to those charges," it said. "Mr. Lomas has not been accused of anything in connection with Bobbi Kristina Brown's injuries." 
 
 Police obtained a search warrant to look through Brown's house, but that's standard procedure, Holland said. 
 
 Concern for Brown came from many in the entertainment world. 
 
 "Poor thing," Warren wrote. "Almost 3 yrs to the day her mom passed and the same thing almost happened to her."
– Condolences are continuing to pour in over the death of Bobbi Kristina Brown, the 22-year-old only child of Whitney Houston who passed away yesterday in Duluth, Ga., after being unconscious for nearly six months. Brown's father, Bobby Brown, has reportedly found some peace in the midst of his grief. "He is taking comfort in the fact that she's with her mother, and that there will be no more sadness or pain," a source tells People. Singer Monica echoed similar sentiments. "You kept telling me life wasn't the same without Mommy," she writes on Instagram. "In all this pain and every tear shed I find a small bit of peace knowing that your [sic] with her again." Houston passed away in February 2012 after being found in a hotel bathtub. Viola Davis was one of many who offered prayers for the Houston and Brown families. "May #BobbiKristina, rest peacefully with her mother in heaven," she tweeted this morning. Oprah Winfrey, Kylie Jenner, Perez Hilton, Taraji P. Henson, and the Rev. Al Sharpton also offered their condolences. "My prayers are with Cissy Houston, Bobby Brown, and the entire family and love ones of Bobbi Christina," Sharpton tweeted. "So sad. May God grant her peace." The Fulton County Medical Examiner's Office will conduct an autopsy, the AP reports, although the length of time Brown spent unconscious will "complicate" its efforts.
