19. Sharon Stone
You don't need this blurb to tell you how, uh, eccentric, Stone is, but we'll indulge you anyway. She flashed her privies as the femme fatale in Basic Instinct, she wears numerous see-through dresses, she babbles at award shows, she lied for years about being in MENSA, and she hinted at bisexuality by saying, "Middle age is an open-minded period." Yeah, we think we got most of it.
