Mixed martial arts starTito Ortiz Monday night said his girlfriend Jenna Jameson had a drug-use relapse and that he apparently confronted her that morning because “I'm not going to let my family go through that.”

Ortiz was arrested by Huntington Beach police shortly before noon Monday after Jameson's father called 911 and an investigation led officers to believe that the mixed martial artist had committed domestic violence involving Jameson. Lt. Mike Reynolds told LA Weekly that officers had enough evidence — physical signs of violence — that they had to make an arrest. Ortiz was booked and later posted $25,000 bail.

“My parents have gone through an addiction and I've seen it in a mirror again,” Ortiz said at a North Hollywood news conference captured by Fox 11 News cameras. “I'm not going to let my family go through that.”

Ortiz's attorney, Chip Matthews, told reporters that Jameson had been addicted to OxyContin and suffered a relapse. Some reports indicated that Ortiz found her “stash” and became upset. The pair have 13-month-old twin boys together.

Matthews, however, said “I want to be quite clear: Tito Ortiz never laid a hand on Jenna.”

Ortiz teared up and took over the conference: “I speak from the heart. I hold everything dear to my heart that Jenna will be okay.”

Both Ortiz and Jameson, the so called queen of porn, had difficult childhoods. Jameson recalls her own hardscrabble childhood, including rape at 16 and underage stripping, in her memoir (with Neil Strauss), How To Make Love Like A Porn Star: A Cautionary Tale.

In a 2007 interview Ortiz told us he gang-banged as a youth, shoplifted food and ended up dealing drugs after high school before a coach from Huntington Beach's Golden West College recruited him for its wrestling team. “I got a second chance in life,” he said.

Jameson contacted him via MySpace when they first met. He said he didn't believe it was really her until she showed up backstage at a fight to meet him.
