This famous couple had to fire their nanny after they got jealous that they were sharing her. This possible presidential candidate has to pay off a mistress. And this singer's man was cheating on her while watching her on stage! All anyone does is cheat these days.

1. "This A/B list celebrity couple with kid/s is currently in couples counseling to address some issues of marital infidelity. Both cheat on a regular basis and it was quietly accepted between the two. Until they each started cheating with the same nanny. Both became extremely jealous and were forced to confront the cheating. Now the nanny is gone and therapy is the newest thing they share." [BuzzFoto]

2. "So, this is not really celebrity gossip per se, but it is tabloid fodder, so I think it works. There is a Republican out there who is in the top three or four potential candidates for President. He wants to desperately run, but is trying to come up with a payoff for his mistress. Cheating is not unusual for him considering he even married a mistress in the past." [CDaN]

3. "She may be an aging diva, but this Grammy winner is still out there performing on a regular basis. During a recent concert, her boyfriend was right there in the third row, supposedly supporting her. Not. While she was belting her heart out on stage, he was offering his heart (and other parts of his anatomy) to a married woman in the audience." [Blind Gossip]
