 Porn queen Jenna Jameson's baby daddy was charged Monday with beating her up at the Southern California home they share. 
 
 Ultimate Fighting Championship star Tito Ortiz, 35, father of Jameson's 13-month-old twin boys, was hauled off to jail in handcuffs from the Huntington Beach house and charged with felony domestic violence. 
 
 Jameson, 36, said she was "completely shocked" that the 6-foot-3, 210-pound Ortiz would assault her. 
 
 "Tito is a loving, sweet man. I've always supported him," said the former XXX-rated leading lady. "For him to lash out at me is shocking." 
 
 Asked if she was going to press charges, the buxom beauty responded, "Oh, yeah!" 
 
 "You have to press charges," said Jameson, who is 5-feet-7 and weighs 110 pounds. "This isn't something you can just get over." 
 
 Jameson's father, Lawrence Massoli, an ex-Las Vegas cop, said his daughter immediately got a restraining order against Ortiz. 
 
 As three cops placed Ortiz in the back of a squad car, the mixed martial arts brawler denied being abusive to Jameson. 
 
 "No," he said curtly when asked by a TMZ.com cameraman if he was being arrested for domestic violence. 
 
 Massoli said he was at the house, which Ortiz owns, when the abuse occurred and called 911. 
 
 Jameson, with her right arm wrapped in a medical brace, said it was the first time Ortiz hit her. 
 
 "I feel completely betrayed," Jameson told reporters outside the house. 
 
 Asked about her injuries, she said, "My arm's okay. I'm tough." 
 
 She declined to disclose what sparked the abuse, but said, "It wasn't minor." 
 
 Police went to the two-story Spanish-style home after getting Massoli's 911 call of a "disturbance" at 9:53 a.m. 
 
 Ortiz, a former Ultimate Fighting light heavyweight champ, was booked at the Huntington Beach Jail. He was expected to be released last night on $50,000 bail. 
 
 The charges have jeopardized his career. "We're going to be fair, but we could cut him," Ultimate Fighting boss Dan White told TMZ. "Other than going on a killing spree, being accused of domestic violence is the worst thing you can have going for you." 
 
 Jameson - the star of such porn classics as "I Dream of Jenna" and "Hell on Heels" - has her own home in Hollywood, but spends most of her time at Ortiz's house. 
 
 Ortiz and Jameson began dating after meeting on MySpace.com in 2006, shortly after she divorced her second husband, on-screen sex partner Jay Grdina. 
 
 In January 2008, Jameson announced she was retiring from porn performing, but would continue to run her $30 million-a-year Internet porn company, ClubJenna.com. 
 
 Jameson gave birth March 16, 2009, to Ortiz's twin sons, Jesse Jameson and Journey Jette. She revealed this month she is launching a singing career. 
 
 ndillon@nydailynews.com ||||| Los Angeles (CNN) -- Former porn star Jenna Jameson was charged with battery over the weekend after police said she assaulted someone. 
 
 The incident took place in Orange County on Saturday evening, police said. 
 
 Authorities released bare-bones information about the incident Sunday night, saying little more than the person who was assaulted made a citizen's arrest and called officers. 
 
 Jameson, 38, knows the person, but Newport Beach Police Lt. Evan Sailor said he didn't know what their relationship was. 
 
 Police took Jameson to the Newport Beach Police Jail. She was later released without having to post bail. 
 
 The battery charge is a misdemeanor. 
 
 No one from the Jameson camp was available for comment. 
 
 On Sunday afternoon, however, Jameson took to Twitter to offer a post that said she was robbed by a friend who "broke into my home and took everything." 
 
 Jameson added that the friend "accused me of gusting her." 
 
 At the height of her success, Jameson was an industry unto herself. She appeared in countless adult films, magazines, and strip clubs -- and as CEO of ClubJenna Inc., launched a film production and online licensing company. 
 
 In a 2004 interview with CNN following the publication of her book, "How to Make Love Like a Porn Star: A Cautionary Tale," Jameson said she chose the right profession. 
 
 "I mean, I've always been so overtly sexual. And I've always been driven to succeed at something that hasn't always been accepted by the American public," she told CNN's Anderson Cooper. "So I think I chose the right profession." 
 
 She retired from porn in 2008. 
 
 In recent years, the mother of twins has found herself in the headlines for her brushes with the law. 
 
 Last May, she crashed her Range Rover into a light pole in Orange County. Police charged her with driving under the influence. 
 
 In April 2010, the father of her twin boys, mixed martial artist Tito Ortiz, was charged with domestic violence when Jameson's father called police as Ortiz and Jameson argued. 
 
 Ortiz and his lawyer told reporters later that he was upset because he thought Jameson had relapsed in her rehabilitation from a prescription drug addiction. 
 
 Four days after the incident, Jameson was captured by cameras alternately saying Ortiz was "the sweetest, most amazing man" and saying that he had beaten her.
– Jenna Jameson's boyfriend has been arrested and slapped with a restraining order for allegedly beating up the porn queen. Ultimate Fighting Championship star Tito Ortiz was taken in handcuffs from the home the two share and charged with felony domestic violence, the New York Daily News reports. Jameson—her arm in a medical brace—told reporters she was "completely shocked" that the mixed martial arts fighter would assault her. "Tito is a loving, sweet man. I've always supported him," she said. "For him to lash out at me is shocking." Ortiz's lawyer insists that his client never touched Jameson and blames the retired porn star's Oxycontin addiction for the incident, according to TMZ.
