There's only one Pam Anderson. The bodacious blonde bombshell celebrated her 41st birthday at LAX Nightclub in Las Vegas on Saturday Night by making a complete sexual spectacle of herself with magician Criss Angel, and diving tongue-first into a birthday cake that was noticeably designed to look like a vagina.

Ah, we love class when it's on full display!

An onlooker said: "Pammie and Criss seemed to be getting on really well. They were making out in a corner for pretty much the whole evening before they moved over to another sofa where they joked and posed for photographers."

Pamela also entertained revellers by erotically licking her vagina-styled birthday cake. The former Baywatch actress was recently reported to have rekindled her relationship with ex-husband Tommy Lee, the father of her two children Brandon and Dylan.

Tommy said last month: "Pamela and the kids have moved back in with me. It's awesome, man. It's definitely working. You can tell on the kids' faces - they're happy when we're together. We've only given it a try 800 times - 801, here we go!"
