LeAnn Rimes cheated but is not a cheater. So there.

leann-rimes-eddie-cibrian.jpgABC's Robin Roberts sits down with LeAnn Rimes for her special "All Access Nashville" on Wednesday (Nov. 3) and the 28-year-old attempts to defend her affair with actor Eddie Cibrian which ended up wrecking both their marriages to other people.

Her basic argument? The heart wants what the heart wants.

"What happened is not who I am, period," Rimes says. "But I do know how much I love him. So I've always said I don't live my life with regret."

Besides, "it happens every day to so many people."

At least Rimes and Cibrian are still together. Which is more than most Hollywood extramarital flings can boast.
