One relationship born from infidelity on both sides is LeAnn Rimes and Eddie Cibrian's. The couple starred together in the Lifetime movie The Northern Lights in 2009 and carried on an affair while filming; LeAnn was married to backup dancer Dean Sheremet while Eddie was married to Brandi Glanville, and their PDA-filled romps were made public by the press.
Despite their scandalous start, Eddie and LeAnn divorced their respective partners and got married in 2011. They share Eddie's two sons from his relationship with Brandi, but the Real Housewives of Beverly Hills star has been more than candid about her disdain for their union. Of the way their romance started, LeAnn has said, "I take responsibility for everything I've done. I hate that people got hurt, but I don't regret the outcome."
