The ex-wife of LeAnn Rimes' husband Eddie Cibrian has told the singer to "go f*** herself".

Brandi Glanville has a history of exchanging verbal blows with Rimes after she allegedly had an affair with Cibrain whilst she was married to him.

Recently, Glanville called Rimes "insane", with the singer admitting that she was getting fed up of the jibes.

Speaking at a Hollywood Q&A for her book Drinking and Tweeting, Glanville went on the offensive again, saying about Rimes:

"She can go f*** herself. Well, she has to, because who would want to?"

Speaking about her failed marriage to Cibrian, she added:

"I did everything I could do for him and the boys and to make him not want to stray. So, when it happened, especially with someone as attractive as her, [it was tough]. When a man cheats on you it's not about you. It's about notoriety. They want to be with you but they want their cake and eat it too."
