I remember when I would use the word “perform” loosely to describe Paris Hilton singing on stage, but even this is a stretch. Here is Jenna Jameson popping out of a styrofoam cake in Las Vegas, putting on a birthday show for her boyfriend UFC fighter Tito Ortiz. This has been called a performance, but it looks like a train wreck–you don’t want to look but you can’t turn away. Seriously. Like, 5 years ago everyone would’ve been swarming around that cake to see Jenna pop out and do a sexy song and dance, but now that she’s just a worn out pile of tanning bed/porno skin with absolutely no good features left on her bony body, no one wants to look. In fact, I’m betting Tito jumped out of his seat when the cake opened up and Jenna came out. He was probably scared. I’m scared just looking at these pictures. If she falls out of that cake, her whole body will shatter to pieces! More pictures of super-skinny Jenna Jameson at Tito Ortiz’s birthday in Las Vegas below.
