Brandi Glanville and Leann Rimes have taken their intense feud to the next level following the former's interview with Bravo host Andy Cohen on Monday evening's 'Watch What Happens Live' (January 21, 2013). Referring to Rimes' recent special for Entertainment Weekly, Glanville said she was growing tired of seeing her children's stepmother on TV, "I feel like every day there's a tell-all interview."

If you're unaware of the pair's history by now, than you probably shouldn't be reading this, but for the sake of the piece: LeAnn Rimes made Brandi Glanville really, really, angry by stealing her husband Eddie Cibrian and marrying him herself. The pair have been feuding in the media ever since. In Glanville's new book 'Drinking and Tweeting' she refers to her ex-husband's new wife as a "sugar mama," and once Cohen brought up the country star, things turned tasty. "Speaking of Rimes," the host asked, "Do you think she is now?" "Insane?" Glanville answered. "Yes, I do." After the show, Rimes took to Twitter to cryptically post, "Wow the texts from my friend. KISSES and KMA."

Glanville - the star of The Real Housewives of Beverly Hills - appears to be moving on from Cibrian anyway, tweeting on Sunday, "Its absolutely impossible to concentrate when ur trainer is a super HOT ex professional soccer player!!!! Way 2 much tension!"
