Pamela Anderson We all know Pamela Anderson ain't a prude Jude.

And back in May we heard tell that she got nekked for her pal Hugh Hefner.

But now we've got the pics to prove it...

Yep, Pam pranced around in her birthday suit for Hugh's 82nd b'day celebration.

Never a shy bean, Pamela presented Hef with a cake in Las Vegas in the nip.

But Hef wasn't the only one to appreciate the starkers revellery...

The Playboy Playmates were tickled pink by the show as Pam appeared from behind a curtain, as bare as the day she was born.

The whole episode has now been aired on their show, The Girls Of The Playboy Mansion, for our viewing pleasure.

But being in the buff isn't only Ms Anderson's domain - oh no, there's a whole heap of garbless stars who've shed their threads.

And being the bodily appreciative bunch that we are, we've collected all these celeb escapades and popped them in the nudey gallery below.
