   Whitney Houston had a deadly mixture of Valium, Xanax and alcohol in her system when she tragically died at the Beverly Hilton Hotel almost two weeks ago, RadarOnline.com is exclusively reporting. 
   
   As previously reported, Valium and Xanax were recovered from the pop icon’s hotel room following her death.

   “Whitney had taken Valium, Xanax, and alcohol, which led to her death. The coroner is waiting on final toxicology results to determine which one of the three was the major contributing factor of her demise,” a source close to the situation tells RadarOnline.com. “The coroner will be closely examining Whitney’s blood alcohol content at the time she died as well. The sedatives and alcohol will almost certainly be the cause of death, and not drowning. Her heart stopped beating because her respiratory system was suppressed because of the anti-anxiety meds, and combined with the booze it probably happened very quickly before she was found partially submerged in the bathtub.”

   Houston’s final days were marred by scandal after she became involved in an altercation at a Hollywood nightclub with another woman, whom she thought was flirting with her boyfriend, Ray J. The 48-year-old was at Tru Hollywood nightclub to support her friend, Kelly Price, who was having a party to celebrate her Grammy nomination. When Price acknowledged her presence, Whitney joined the stage and began to sing Yes, Jesus Loves Me. 
   
   The pop star emerged from the nightclub that evening looking disheveled, intoxicated, and had blood running down her leg. Eyewitnesses have said Whitney was drinking heavily and doing tequila shots in the VIP area.

   REPORT: Bobbi Kristina Got High After Whitney Houston’s Funeral ||||| Four years ago, Whitney Houston's ex-husband, Bobby Brown, planned to sell a tell-all book about his life with the superstar. And although that book was never published, some say Bobby is once again trying to make it happen. 
   
   "Back in 2008, the interest in a book on Whitney Houston wasn't that great," a major publisher tells me. "Whitney had fallen off the radar back then ... but now, following her tragic death, the market has changed. Now is the time for a book that details an honest look into the life of Whitney." 
   
   But standing in Bobby's way is the confidentiality agreement he signed when his divorce was finalized, plus the impact that a tell-all would have on his daughter, Bobbi Kristina. 
   
   "Bobby loves all his children," his former attorney, Phaedra Parks told me days after Whitney died. "He would do anything to protect all his children." 
   
   But friends of Whitney tell me they are not so sure. 
   
   "This is a man who left his ex-wife's funeral because he didn't like his seats and went to a paying gig that night," a friend of the diva tells me. "He didn't get on stage that night because he needed to sing his greatest hits or because Whitney would have wanted him to entertain his fans, he did it to get a paycheck -- the same reason he now wants to write a tell-all book."

   Earlier on HuffPost:
target: – Whitney Houston was killed by a combination of Valium, Xanax, and alcohol, an insider tells Radar. All three were found in her system, but the coroner is still waiting for toxicology results before the "major contributing factor of her demise" can be determined, the source says, adding that drowning is almost certainly not to blame: "Her heart stopped beating because her respiratory system was suppressed because of the anti-anxiety meds, and combined with the booze it probably happened very quickly before she was found partially submerged in the bathtub." (In other Whitney news, sources say Bobby Brown is shopping a tell-all about their life together.)
