Kristen Stewart has been branded a ''homewrecker'' by Brandi Glanville.

The 'Real Housewives of Beverly Hills' former husband Eddie Cibrian dumped her for Leanne Rimes and Brandi took to her twitter page to hit out at Kristen's recent dalliance with married director Rupert Sanders and launch a not so subtle attack on her ex and his new wife.

She wrote on twitter: ''I'm not happy with this K stew BS,' she posted on Wednesday. '2 close to home. Same story, friends with the wife and kids & f*** the husband when we think no one is looking.

''My last quote of the day on this subject- Home-wreckers come in pairs #ittakes2 (sic).''

Brandi's not the only one who is angry with the pair, Charlize Theron is reportedly outraged that her 'Snow White and the Hunstman' co-star cheated on Robert Pattinson because she is close friends with the 41-year-old filmmaker's wife, Liberty Ross.

A source close to Charlize said: ''Charlize is absolutely fuming with Kristen for having an affair with Rupert.

''She is very tight with Liberty, has spent time with the family and cannot believe Kristen has done this.

''When they were all filming 'Snow White and the Huntsman', Charlize felt like an older sister to Kristen, and they were always sharing advice.

''Charlize had no idea what was going on between Rupert and Kristen and now feels completely betrayed by the whole incident.

''It's certainly left Charlize between a rock and a hard place, because she feels great sympathy for Liberty and the kids and yet, she has a sisterly love for Kristen.''
