When Karma Strikes: Celebrity Cheaters Who Played, Then Got Played

The saga of Bennifer began just as it ended: in ignominy. In 2001, the world folded in on itself when J-Lo broke up with hubby Cris Judd only to start dating Ben Affleck. Fifteen years later, J-Lo seemed to get her just deserts when a slightly different handsome backup dancer, Casper Smart, cheated on her.

Jackass star Bam Margera claimed on Howard Stern's radio show in 2006 that he and Jessica Simpson had hooked up while Simpson was still with Nick Lachey. She is also rumored to have hooked up with Johnny Knoxville and Adam Levine while she was still with Lachey.

Six years later, Simpson's second husband, Eric Johnson, was embroiled in a cheating scandal of his own - with his ex-wife Keri. Some sources also claim that he disappeared into some bushes with their nanny for two hours.

Despite forcing wife Téa Leoni to put up with his sex addiction for years, Californication actor David Duchovny divorced Leoni after a brief affair she had with Billy Bob Thornton. 

Jon Gosselin has long denied that he cheated on Kate Gosselin, but no one believes him. On a 2014 episode of Couples Therapy with Dr. Jenn, Jon's girlfriend Liz Jannetta not only called him out on his lying but also admitted to cheating on him.

LeAnn Rimes and husband Eddie Cibrian started a fling in 2009 on the set of Northern Lights - while they were both married to other people. Cibrian's wife at the time, Brandi Glanville, rode her husband Cibrian's cheating scandal all the way to a starring role on a reality show, so she wasn't about to miss an opportunity to go public about her own cheating with Cibrian. She even went so far as to mail Rimes proof of his indiscretions.

In Frank Sinatra's heyday, he could have any woman he wanted - and he did, even while he was married to wife Nancy Sinatra. It seemed he'd turned a new leaf once he'd met his one great love, Ava Gardner, but he never would have predicted that he could be the one cheated on. After allegedly confiding to friends that Sinatra could no longer satisfy her sexually, Gardner ran off with a bullfighter.
