Ronald Richards, Jameson's attorney, told RadarOnline.com that the mixed martial arts champ's claim is "false and irrelevant."
"You can't hit your spouse even if they are under the influence of anything," Richards told the gossip site.
Ortiz blamed Jameson's drug use for his arrest Monday on suspicion of domestic violence.
The former UFC light heavyweight champion was arrested 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 drug addiction and claimed Ortiz never struck her.
"Jenna Jameson has been fighting an ugly battle with an addiction to Oxycontin for well over a year, and this morning, she had a relapse," Ortiz's attorney Chip Matthews said. "We're here because Tito was trying to help her. Tito Ortiz never laid a hand on Jenna."
