LeAnn Rimes Talks Infidelity & Her Ex

LeAnn Rimes Talks Infidelity & Her Ex

No topic was off limits when LeAnn Rimes sat down exclusively with ET's Nancy O'Dell.

The country superstar, whose controversial relationship with husband Eddie Cibrian has become both a blessing and a curse, tells Nancy her upcoming album Spitfire was born unexpectedly during her extra-marital affair with Eddie. In fact, a handful of infidelity themed tracks included in the album were initially written about a friend of hers while LeAnn was married to her ex, Dean Sheremet.

"What Have I Done is one of the first songs that I wrote for the record, before anything was actually starting to happen," said LeAnn. "It was written about a friend of mine, but I didn't realize I was writing it for myself at the time... It was my subconscious talking and I didn't know yet."

Speaking on the feelings that sparked her and Eddie's infamous affair, LeAnn acknowledged that her then husband had heard the troubling track and perhaps knew she would soon be led astray.

"He actually heard the song when I wrote it and, actually, he knew what it was about before I did," she reveals. "He knew I was feeling feelings. I'm not sure what those were that he knew."

When asked if she ever worries whether her husband Eddie would ever cheat on her, LeAnn admits that she does.

"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," said LeAnn, going on to reveal that Eddie has had the same concerns about her.

"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."
