Brandi Glanville weighed in on Kristen Stewart's fling with married director Rupert Sanders. The reality TV star, whose marriage went kaput following then-husband Eddie Cibrian's affair with LeAnn Rimes, branded the "Twilight Saga" actress a "homewrecker."

"I'm not happy with this K stew BS.2 close to home.Same story,friends with the wife and kids& f*** the husband wen (sic) we think no one is looking," Glanville wrote to her followers. "My last quote of the day on this subject- Home-wreckers come in pairs #ittakes2."

While "The Real Housewives of Beverly Hills" star blatantly slammed the 22-year-old brunette beauty, Lady GaGa sang different tune. "This Stewart-Pattinson stuff is brutal. Makes me sad the way press acts. Hope they are ok," she reportedly tweeted.

Stewart and Sanders worked together in "Snow White and the Huntsman". She played the titular princess, while he served behind the lens. In a stomach-churning twist, his wife Liberty Ross portrayed the on-screen mother of Stewart's character.

Stewart's affair with Sanders did not only put the director's marriage into jeopardy but also rocked the actress' relationship with Robert Pattinson. The British heartthrob reportedly has moved out of the Los Angeles home he shared with Stewart.
