Kristen Stewart Cheated for Months, Believes Rupert Sander's Wife

Kristen Stewart had been cheating on Robert Pattinson with 'Snow White and the Huntsman' director Rupert Sanders for months, believes Rupert's wife Liberty Ross.
Liberty, 33, a former vogue model met Sanders as a teenager. After their marriage she followed him to Hollywood where she dutifully looked after their children Sklya Lily, 7, and Tennyson, 5, while he made his career.
She is now seething with anger, despite Sander's public apology to her, her brother Leopold, a British rock guitarist based in Los Angeles, tells British tab The People.
Leopold claims, Sanders affair with Stewart was long drawn.
"It was from the last half of filming and all through post-production, clear into last week," he says.
"She made some sacrifices for something she thought was worth it, now she knows, right? Five minutes from her home," Leopold laments.
Sanders and Stewart had a steamy makeout session on July 17 at Pacific View Trail that offers a view of the HOLLYWOD sign, at the end of which she drove him to his place and dropped him three blocks away from his home.
Leopold says Liberty will get through the crises because their family is close knit. A break-up might even do her good since she had been unhappy with the marriage for some time.
Stewart's friends tell The People that her cheating on Robert may have been prompted by his friendship with his Remember Me co-star, Australian actress Emilie de Ravin, 30.
Robert and Emilie became friends on set in 2009. Later, when Emilie's marriage to Josh Janowi unraveled she turned to him for support.
"Nothing romantic ever happened between them but it didn't make Kristen feel any better about them being so close. Emilie was at a very low ebb. She was going through a split and she and Robert made one another laugh," says The People source.
