(AP) — Mixed martial arts star Tito Ortiz claims his ex-porn star girlfriend is addicted to Oxycontin, and he's blaming Jenna Jameson's drug use for his arrest on suspicion of domestic violence.

Ortiz was arrested Monday morning in Huntington Beach at the home he shares with Jameson and their twin sons. Several hours after posting bail, Ortiz and his attorney accused Jameson of being a drug addict and claimed Ortiz never struck Jameson.

Ortiz is a former UFC light heavyweight champion whose celebrity has eclipsed his MMA accomplishments in recent years. He wept openly at the hastily arranged news conference in North Hollywood.

Attorney Chip Matthews says Ortiz found drugs in their home, leading to the confrontation that ended with Ortiz's arrest.
