LeAnn Rimes began her affair with Eddie Cibrian when they were both married to other people, and she dropped the bombshell news that she worries now that he will cheat on her!

In an interview with Entertainment Tonight, Nancy O’Dell asked LeAnn, 30, if she worries that Eddie will cheat since he was married to Brandi Glanville when they first hooked up.

“I would be ignorant to say, and everyone else would think I am a liar if I didn’t say yes, and I have at times,” LeAnn admits.

She also says that since she was married to Dean Sheremet when she started the affair, Eddie, 39, fears she will cheat on him too.

“Speaking for him, I would actually say that’s creeped into his mind…I think we’ve been very honest and open with that to each other and our conversations about it have only made me understand how much he actually cares, as much as I do, about being faithful to each other.”
