DEMI MOORE

Who knew back in 1991 when the actress posed pregnant – and in the buff – for the August cover of Vanity Fair she would start a bump-baring trend? "The shot that ended up being on the cover wasn't even done for the magazine," Moore revealed to V magazine in '08. "Then [photographer] Annie [Leibovitz] called, we kind of joked, and I said it would be amazing if they would do this on the cover." And that baby is now a young lady: Scout, Moore's second of three daughters with ex-husband Bruce Willis, was born a month after the talked-about cover.
