MMA fighter Tito Ortiz was taken to jail last night after being arrested for felony domestic violence involving girlfriend Jenna Jameson. I guess a porn star’s life isn’t always the fairytale you’d think it’d be. TMZ says

Jenna Jameson claims Tito Ortiz got very violent — throwing and injuring her.

Jenna claims that during an argument Monday morning she, “said something very hurtful to his ego.” She alleges that Tito then grabbed her and, “threw me into the bathtub and tore two ligaments in my shoulder.”

Tito’s attorney strongly denies that, saying … “He did not put his hands on her, he did not hit her, he did not do anything to her.”

Tito claims he only confronted her about the narcotics he found in her pants pocket when she had an “emotional meltdown.” His version:

Tito Ortiz claims that Jenna Jameson is addicted to Oxycontin — and that’s what led to the alleged domestic violence.

Jenna’s been battling addiction to the painkiller for more than a year now, and that Tito and family members have been protecting her. Jenna had a relapse and that Tito confronted her about the drugs he found.

Tito was very choked up when he said he hopes “Jenna will be okay.”

[Ortiz' attorney] says Jenna has been to rehab, and that her addiction has led to multiple suicide calls to 911.

It’s easy to mistake losing your balance and headlonging it into a tub for domestic physical assault when you’re high on opioids. It’s also easy to mistake being forcibly restrained with handcuffs for an amorous embrace that should be reciprocated with aggressive sexual advances. That’s why I never tongue-kiss or grab the wiener of anyone with a uniform and a gun anymore, no matter how tightly they might have been holding me.
