Tito Ortiz -- Jenna Is Hooked on OxyContin

After Tito Ortiz was arrested yesterday morning for domestic violence, Ortiz  and his attorney claim Jenna Jameson is addicted to OxyContin -- and they say that's what led to the alleged incident that got the UFC fighter busted for felony domestic violence.

Ortiz dropped that bombshell during a news conference at a restaurant in North Hollywood.

Tito's attorney Chip Matthews said that Jenna's been battling addiction to the painkiller for more than a year now, and that Tito and family members have been protecting her.

Tito was very choked up when he said he hopes "Jenna will be okay."  Tito also said, "My parents have gone through addiction and I'm not going to let my family go through that."

As for what happened in Tito and Jenna's home Monday morning -- Jenna claims that Tito grabbed her and, "threw me into the bathtub and tore two ligaments in my shoulder." Jenna also says the incident between her and Tito "wasn't minor" ... but she still wants to work things out with him for the sake of their two twin boys.

Matthews repeatedly said, "Tito never touched Jenna."   He claims that Jenna had a relapse and that Tito confronted her about the drugs he claims to have found.  Matthews suggested Jenna was high and just lost her balance.

Matthews claimed Jenna has been to rehab, and that her addiction has led to multiple suicide calls to 911.

So what's Jenna's side of this?  During the news conference the former porn star was packing up to leave for Las Vegas.  When told about Tito's allegations, she said "he's trying to save his career" -- and then hit the road for Vegas with two friends.

Jenna and Ortiz first meet on myspace in 2006 and in March of 2009 had twin boys together. While Jenna is in Las Vegas her father will be taking care of their two sons.
