TMZ is reporting that police units have responded to a “disturbance” call at Tito Ortiz and Jenna Jameson’s house in Huntington Beach, California. Details are scarce at the moment, however TMZ is also hearing that crime scene investigation units are on scene as well which seems to imply that this is something a lot more serious than a loud argument a neighbor overheard.

Updates will be posted below…

Update: Word is Tito Ortiz has been arrested for domestic violence.

TMZ has learned Tito Ortiz was just arrested for felony domestic violence at the home he shares with Jenna Jameson.

We’re told when cops arrived at the couple’s home in Huntington Beach, CA — Jenna Jameson had “visible injuries.”

We’re told someone called 911 today at 9:53 AM and reported a “disturbance.”

Tito is currently in custody and on his way to a Huntington Beach jail in Orange County, CA.

Update 2: Videos via TMZ:

Jenna says she’s pressing charges

Update 3: Jenna is suddenly wearing a brace on her right arm.

Update 4: Dana White has weighed in on the situation and says they could cut Tito.

White says, “We’re gonna be fair, but we could cut him.”

White wants to wait until the police reports are in, but the UFC can take action even before the legal process runs its course. “Other than going on a killing spree, being accused of domestic violence is the worst thing you can have going for you,” White says.

Update 5: Tito is being held on $25,000 bail.

Update 6: Jenna won’t say what Tito did but it appears the only visible evidence of any abuse is the brace around her arm. She already has a restraining order. Says it was the first and the last time. The kids are fine.

I am completely shocked. Tito is a loving, sweet man, and I’ve always supported him through everything. For him to lash out at me like this is shocking, and I feel completely betrayed, completely betrayed.

Update 7: The 911 call said “a boyfriend had pushed his girlfriend down.” There’s no evidence of Tito striking Jenna at this point. Tito was released on bail around 4PM PT.
