Not long ago, Jenna Jameson announced at the porn awards that she'd never spread her legs again in the business.

Well, she may not have spread 'em this past weekend, but she certainly did some bumping and grinding.

Of course, it was all for a good cause. Her boyfriend, Tito Ortiz, was having a birthday party at the Cathouse club in Las Vegas. When such elements are in alignment, it would be offending the bacchanalian gods not to have Ms. Jameson do a burlesque take on the Marilyn Monroe rendition of "Happy Birthday."



Photos of the performance and more Jenna after the jump.
