Once a cheater, always a cheater?
If that's the case, you might wanna stay away from the following celebrities... no matter how attractive they are, no matter how well they dunk a basketball or how impressive they are in front of a camera.
Indeed, infidelity is not reserved for athletes or singers; male or females.
Stars from all industries have strayed from their significant others - and while some have rebounded with hot new mates (darn you, Mila Kunis and Lindsey Vonn!), all hopefully regret the actions that landed them there.
