I love a wardrobe malfunction, but when a nip slip is left in a movie I can't help but wonder: was that actually on purpose? After all, editors combed through hours of footage to create the scene in front of us where a nipple is freed. Is it possible the nipple was in every shot? Is it on purpose? Or did the editor give the entire world a gift and the director was so pleased that he okayed it? Whatever the reason, here are famous movie nip slips:
