And the Gold Medal winner is ... Applause for Charlize Theron!
This South African beauty's breakthrough role was coincidentally her first nude foray, in the steamy "2 Days In The Valley."
"She's the ultimate old school beauty with a modern edge," says DeLillo, "she is captivatingly different in every picture."
"With a face like that, she doesn't need rock hard abs," adds Rogne. But we'll take them anyway!

And the Silver Medal goes to ... Jenny McCarthy!
From MTV, to Playboy to one of Oraph's christened gurus, McCarthy "looks amazing, even after having a child" according Rogne.

And the Bronze Medal goes to ... Pamela Anderson!
While acting certainly defined her later career, going au natural is something Anderson has always been successful in choosing.
"Though the size of breasts may frequently change, she remains a beauty," says Rogne.
DeLillo thinks she "transoformed the bikini stereotype from skinny to hottie lifeguard," adding serious proportions to the classic frame.
