TITO ORTIZ BLAMES HIS GIRLFRIEND JENNA JAMESON'S OXYCONTIN ADDICTION FOR HIS ARREST!

She was high on drugs and must have fallen.
That's Ultimate Fighting Championship star Tito Ortiz claims his gal pal, porn diva Jenna Jameson, hurt her arm - not domestic violence.

Ortiz, 35, was arrested Monday after the couple got into an argument and Jameson called the cops. Ortiz was charged with felony domestic violence, but his lawyer said he's innocent.

"Tito Ortiz never laid a hand on Jenna. Never," said attorney Chip Matthews during a press conference in North Hollywood, according to TMZ.com.

Ortiz said James, who is the mother of his 13-month-old twin boys, was high on Oxycontin and has been addicted to the prescription pain killers for more than a year.

"My parents have gone through addiction and I'm not going to let my family go through that," he said.

Matthews said Jameson, 36, suffered an "emotional breakdown" because of her addiction

"Unfortunately when there's drug use, a lot of times people want to play the victim," he said. "Tito tried to help her."

Jameson, 36, shot back saying "he's just trying to save his career."

The 5-foot-7, 110 lbs. former XXX-rated actress tried to play down the incident, calling it an "altercation."

"He never beat me," she said. "If he beat me, I'd be dead."

Jameson's father, Lawrence Massoli, an ex-Las Vegas cop, was home during the argument and called 911.

Matthews said Massoli supports the 6-foot-3, 210 lb. mixed martial arts fighter - and is "on his side." Ortiz teared up and abruptly left the press conference when Matthews talked about the couple's future.

"They have two children together and they plan to spend their lives together," Matthews said.
