Whether a multiple offender (think Tiger Woods) or a one-time adulterer (Kristen Stewart), these celebs have had the humiliating task of publicly admitting to and in some cases apologizing for cheating on their significant others. Suffice it to say, most of their relationships never recovered.
After meeting on the set of TV movie Northern Lights, both stars cheated on their respective spouses — Dean Sheremet and Brandi Glanville. After issuing statements admitting their wrongdoing, the pair got divorced and married each other in 2011.
