LeAnn Rimes admits she was "selfish" to have had an affair with married actor Eddie Cibrian.
The 27-year-old singer grew increasingly close to her co-star in TV movie 'Northern Lights' in 2008 and were regularly seen together even after filming ended, leading to the end of her seven year marriage to dancer Dean Sheremet.
She said: "I did one of the most selfish things that I possibly could do, in hurting someone else.
"I take responsibility for everything I've done. I hate that people got hurt. Bt I don't regret the outcome."
Discussing the affair with Eddie – with whom she is now in a committed relationship with after he ended his marriage to Brandi Glanville – LeAnn said: "It was very emotionally driven. I never once thought what I was doing was ok."
She also admits her marriage to Dean – who she is close to finalising divorce proceedings with – wasn't right for either of them.
She added to People magazine: "It wasn't a marriage the fulfilled either one of us."
LeAnn and Dean's divorce is expected to be completed on June 19, although the details are expected to remain private.
