Our chin hit the floor this morning when we heard reports that Kristen Stewart has cheated on Robert Pattinson.
Kristen, 22, has allegedly had a fling with the director of her latest film Snow White And The Huntsman, married 41-year-old father-of-two Rupert Sanders.
Filming on SWATH finished months ago, but US gossip magazine Us Weekly claims to have photographic proof of the fling – with Kristen pictured wrapped up in the arms of Rupert just last week.
Meanwhile, People.com is reporting that Kristen is devastated over her “lapse in judgement”,
“Kristen is absolutely devastated. It was a mistake and a complete lapse in judgement. She wasn't having an affair with Rupert,” the source claims.“It was just a fleeting moment that shouldn't have happened. She never meant to hurt anyone. She's a good person who just made a bad choice.”
Twilight couple Robert and Kristen met on the set of the vampire movies that made them famous, and have always been careful to keep their relationship as private as possible.
Rob recently expressed his disproval of cheating, telling Italian Vanity Fair that he believes it is possible to stay with one person forever,
“There is one thing I've never understood: Why people cheat. My parents met when my mom was 17 and my father 25, they are still together, and seem very happy.”
Director Rupert Sanders is married to model Liberty Ross, 33 and they have two children together.
