Jenna Jameson's Boyfriend Tito Ortiz Arrested for Domestic Abuse

Ultimate Fighting champ Tito Oritz was arrested Monday morning after an altercation with girlfriend Jenna Jameson at their home in Huntington Beach, Calif.

According to police, the porn star's dad called 911 around 10 a.m., after which Oritz, who has been dating Jameson for three years and is the father of their twin sons, was apprehended on a domestic violence charge around noon.

Jameson, 36, wouldn't comment on what exactly went down between her and Ortiz, but was seen wearing an arm brace later in the day.  "Tito is a loving, sweet man and I've always supported him through everything," she told TMZ.com. "For him to lash out at me like this is shocking, and I feel completely betrayed...And I feel bad for my children."

She also added that she plans to file a restraining order against Ortiz, 35.

Ortiz was released on $25,000 bail Monday night, while the fighter's attorney called a press conference, in which he claimed there was no violence between the couple and that Jameson is addicted to painkillers.

"Jenna has been fighting a battle with OxyContin addiction for the past year. For Tito and her family this has been an uphill battle. Unfortunately this morning she had a relapse," Chip Matthews told reporters. "Tito was trying to help her, she has threatened suicide before. Tito has done everything in his power to protect her privacy and the privacy of their children."

"When you're dealing with people on OxyContin they don't always have the best sense of balance," Matthews continued. "Jenna and Tito have two children together, they planned on spending the rest of their lives together. They want nothing more than to work together on this."
