Cheater: Eddie Cibrian
Date Of Affair: Mid November 2008 - Present

It was a wrap for Grammy-winning country star LeAnn Rimes' rep as one of America's sweethearts when she surprised fans in late March of 2009 with rumors of an extramarital affair with actor Eddie Cibrian. The two-timing allegedly began four months earlier while shooting the Lifetime TV movie Northern Lights in Calgary, Canada. The fact that Cibrian, who has appeared on CSI: Miami and Ugly Betty, was married with two sons, didn't help either.

The svelte singer's six-year marriage to husband Dean Sheremet ended and the backlash from fans started. "I don't think the way I did it was right," she admitted later to Shape Magazine about her new relationship. The cheating couple did, however, try to do the right thing when they got married to each other this past April. Let's see if the still lovely-looking singer can get back some of the luster she lost after folks started calling her a LeAnn "Two Times."
