Top 15 celebrities who cheated on their spouse (With Pictures)

3. Billy Crudup

Seven months pregnant, Weeds star Mary Louise Parker found out her boyfriend Billy Crudup was having an affair with Homeland star Claire Danes. Labeled a homewrecker, Claire was only 24 when she did her part in breaking up the eight year relationship between Billy and Mary Louise. Not only did Billy cheat on Mary Louise, he decided on his own volition to leave her as well, barefoot and pregnant and now alone. Crazily enough, Mary Louise named their baby after his philandering dad, which means Billy didn’t have to lose all that much. Again, another very sorry cheater.
