Jenna Jameson Pulls Plug On Marriage

Porn queen Jenna Jameson has filed for legal separation from her husband of three and a half years.

TMZ obtained the legal papers, filed in Los Angeles County Superior Court. Jameson, whose legal last name is Massoli, has been estranged from husband Jay Grdina. Grdina, also a porn star, performs under the name Justin Sterling.

The couple has no children, however, we're told the divorce could get nasty. Sources tell TMZ the couple has no prenup, but Jameson is rolling in dough after selling her lucrative business to Playboy. Jameson is repped by mega-celebrity lawyer Neal Hersh.

Jameson, once linked to rocker Dave Navarro, has been keeping company with Ultimate Fighting champion Tito Ortiz. The couple has been spotted partying it up in Vegas and Los Angeles, and was most recently spotted in the green room at VH1's Big in '06 awards.

So it's a little bittersweet -- yes, Jenna's available, but you'll have to go through Tito Ortiz to get to her. Good luck, boys!
