Former adult-film star and erotic entrepreneur Jenna Jameson plans to press charges against her live-in boyfriend of four years, UFC mixed martial-arts fighter Tito Ortiz, following his arrest at their Huntington Beach, Calif., home Monday after being accused of domestic abuse.

Jameson, whose twin sons Jesse Jameson Ortiz and Journey Jett Ortiz were born in March 2009, tearfully replied, "Of course" when a videographer at the scene asked whether she planned to file charges. She wore a bandage wrap over her right elbow and upper arm as she left her house and drove away with her father, Lawrence Massoli, her children and their nanny.

Massoli had made the initial domestic-disturbance call to 911 at 9:53 a.m., TMZ reported.

"My babies are all right. . . . Everything's OK. . . . He's in jail," Jameson said of Ortiz, who was taken to an Orange County lockup.

Jameson, who the previous night had happily tweeted that she and Ortiz were dining at the Huntington Beach restaurant Sushi On Fire, posted Monday that, "I'm sorry to all of my fans, but I'm going to be quitting Twitter. I cant take any more abuse from ANYONE . . . To my sweet fans . . . thank you."

As for Ortiz's fans, they may or may not be able to find him back in The Octagon - UFC president Dana White told that the fighter's career may be KO'd. "We're gonna be fair, but we could cut him," he said, adding that he would wait to see the police report. "Other than going on a killing spree, being accused of domestic violence is the worst thing you can have going for you."
