An emotional Jenna Jameson breaks into tears on camera while describing her alleged altercation with boyfriend Tito Ortiz that ended with the mixed martial arts fighter's arrest April 26 in Huntington Beach on suspicion of felony domestic violence.

Jameson told Us Magazine that she and Ortiz had an "incredibly personal" argument  "It was sexual"  at the end of their Sunday date night. In the morning, she says, he accused her of using drugs and began packing his things. She says she pleaded with him and offered to take a drug test. He told her it was over, she says, and grabbed her arm and pushed her as he moved past her; she fell onto the edge of a bathtub.

It's unclear when the interview was conducted; the couple, who have twins together, had backed down Thursday after hurling accusations at each other ...... through the earlier part of the week. The two spoke to each other Monday night for the first time since

Jameson says that when law enforcement took Ortiz to jail -- her father had called 911 -- she didn't want him to go. She calls him "so loving" and "so protective," but also alleges a previous episode of violence that she attributes to the effects of a spiked drink. "I'm so in utter shock that this happened," Jameson says. "Because we were America's couple."
