Michael Douglas & Catherine Zeta-Jones

Michael Douglas and Catherine Zeta-Jones had a similar clause—on top of the $2.8 million Zeta-Jones receives for each year of marriage, she would also get a $5 million bonus if Douglas were ever caught cheating. But good luck finding anyone more ridiculously beautiful to cheat on. Zeta-Jones has said she thinks pre-nups are "brilliant." Yeah, I would agree if I was making that kind of bank for sleeping with an older man. I usually just smell like Ben-Gay afterward. [Aisle Dash]
