Bruce Willis and his 24-years-younger model girlfriend, Emma Heming were wed in Parrot Bay this weekend, to the attendance of Demi Moore and Ashton Kutcher. While in town for the wedding, Ashton Kutcher took the opportunity to twitter about Bruce Willis' previous wife wearing a bikini and then took a picture of her ass in it.

God, it's like the guy has never seen a woman in a bikini before. Or his wife's ass. Or his wife's ass in a bikini. Or a toasted sub from Quizno's. Yeah, on that last one, let's hope he never finds out or we'll never hear the end about how cheesy, delicious and toasted to perfection it was.
