The drama continues in the alleged affair between LeAnn Rimes and her 'Northern Lights' co-star, Eddie Cibrian. While LeAnn has refused to directly address the rumors, Eddie has vehemently denied any wrongdoing. Now, the actor's wife is speaking out.

"LeAnn is a stalker," Brandi Glanville tells Us Magazine. "She refuses to leave us alone. It is shameful and scary. People are going to say it takes two to tango and I get that, but at some point LeAnn needs to stop asking him to dance."

Brandi, a model and mom to Eddie's two young children, says her husband has had to change his phone number because of LeAnn's "constant texting and calling." She also accuses the country singer of following her husband to an L.A. Lakers game, where the two were photographed chatting.

"These comments are incredibly defamatory," a spokesperson for LeAnn tells PEOPLE magazine, in response to Brandi's claims. "While there are always two sides to every story, LeAnn continues to remain above the fray and chooses not to play this out in the press."

Brandi, on the other hand, tells the press that she and her husband are trying to put their lives back together after the scandal -- an effort she says LeAnn is trying to hamper.

"I'm a happy wife fighting for what I have," she tells Us. "LeAnn is so desperate for fame she has left her self-respect in the gutter and doesn't care who she hurts to get what she wants. She's hurting my family and messing with the wrong mom."

LeAnn, married for seven years to dancer Dean Sheremet, has been frequently photographed flashing her wedding ring to paparazzi in the last few weeks, yet she's remained tight-lipped about the infidelity allegations. A source claiming to be close to the singer tells Us, "Eddie and Brandi are both on the record on this and LeAnn has kept quiet, so what does that tell you about who is after fame and press?"
