After being arrested following an alleged domestic dispute against girlfriend Jenna Jameson on Monday morning, a teary-eyed Tito Ortiz held a press conference with his attorney in Los Angeles late Monday evening to speak for the first time with regards to the incident in which he alleged Jameson is suffering an addiction to the narcotic pain reliever, OxyContin.

"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," attorney Chip Matthews said. "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."

According to Matthews, on Monday morning the UFC champ confronted his girlfriend (and mother of their twin boys) about the drugs he had found and she denied it. Jameson was allegedly suffering an "emotional breakdown", prompting a 911 call from Jameson's father Larry who was reportedly not in the room at the time of the confrontation.

Matthews also reinforced numerous times that Ortiz never ever laid a hand on Jameson.

"It means the world to me, my friends and family for their support. My parents have been through an addiction and I see it in the mirror again. I am not going to let my family go through that," a sobbing Ortiz told us. "I speak from my heart, I hold everything dear to my heart that Jenna will be okay."

Matthews also claimed that Jameson's family have now sided with Tito since learning his side of the story, and are well aware of her alleged drug problems that they tried for so long to keep this out of the public eye.

He also insisted that the police do not have to have visible signs of injury to make an arrest in domestic disputes, and that the police report indicated that Jameson had "a scratch on her elbow" which may explain why she was photographed leaving a CVS pharmacy wearing a medical brace on her right arm just hours after the arrest.

"When you're dealing with people on OxyContin they don't always have the best sense of balance," Matthews added. "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."

It is unclear if Ortiz and Jameson's children are with their mother, however Matthews assured us that they are "well taken care of".

Ortiz remained quiet for most of the conference and was unable to directly answer questions due to the ongoing criminal investigation surrounding the incident. But after just a few minutes the UFC fighter broke down and bolted from the room, in which Pop Tarts heard him hysterically crying.

A rep for Jameson was not immediately available for comment.
