LeAnn Rimes to Brandi Glanville: Back Off Lady!

LeAnn Rimes is straight hating on her boyfriend's wife. Don't we all?

A source close to Rimes' soon-to-be divorced lover, Eddie Cibrian, says that Rimes' lawyers sent a cease and desist letter to his estranged wife Brandi Glanville.

The reason? Allegations of slander. A lawsuit may follow imminently.

Rimes' claims stem from before Eddie and Brandi even split. Amid rumors of Rimes' affair with her husband, she told the press LeAnn was stalking Eddie Cibrian.

Of course, the source explains, Brandi Glanville was unaware of the Lifetime movie co-stars' affair, and only made that statement before Cibrian broke the news.

Despite making no secret of being royally pissed at Eddie Cibrian dumping her for LeAnn Rimes (right), Brandi Glanville (right) denies slanderous wrongdoing.

"Brandi has been nothing but nice to LeAnn," says a source. "She let her kids go to Mexico with them, and is happy they like her. If they didn't, she would be upset."

Things have been relatively quiet on the Rimes-Cibrian-Glanville front recently, which makes news of Rimes' out-of-the-blue cease and desist letter more shocking.

Rimes' camp says it came "after months of Brandi speaking about LeAnn in the press and telling lies. This is something she felt was necessary to protect herself."

Rep for both Rimes and Glanville had "no comment" on this, but sources close to the latter say her attorneys plan on responding to the letter in the coming days.

Meanwhile, Glanville and Cibrian's divorce is getting close to being official. We just hope there are no more tire slashing rampages from Brandi in the meantime.
