Millions of men worldwide have watched her doing very very naughty activities... but never for beating someone up!

The ex-porn star Jenna Jameson, whose birth name is Jenna Marie Massoli, was arrested Saturday night after a report that she attacked someone at their Orange County home.  The arrest came on the night she was planning on celebrating her upcoming 39^th birthday at Heat Ultra Lounge, but the XXX star was whisked away with handcuffs before the shindig even kicked off.  Later that night she was released from jail, never making her own birthday party.

Newport Beach police Lt. Evan Sailor says the alleged victim put Jameson under citizen's arrest until police arrived at the upscale home on the Balboa Peninsula. 

Wild Jameson has been pre-partying for an entire month now starting the festivities at The Crazy Horse Gentlman's Club in Las Vegas in March with a string of all night benders ending on Saturday by the police.  This arrest should mark the end of her indulgent binge, but if we're going by her recent history, this sex worker will not learn from her mistakes and keep the party going.

Last year, the blond was arrested for a DUI after she crashed her Range Rover into a light pole in Southern California.  She pled guilty and was sentenced to three years of probation, a $340 fine, and was ordered to participate in Mothers Against Drunk Driving.  There is no word how the newest battery charge will affect her probation.

While she's never been much of a saint, the repetitive outlandish behavior is less palpable with the delivery of her twin boys Jesse and Journey in March 2009. Growing up with your mother being a porn star is going to be awkward enough for the three-year old; she really doesn't need to be throwing more wood into the fire.

So Jenna: Put down the shots of "Jameson," stay home, and be a stable sober parent making headlines for something other than embarrassing arrests.
