Kristen Stewart Cheats On Robert Pattinson With Married ‘Snow White And The Huntsman’ Director

Looks like their love is not quite so eternal after all, at least not in real-life. "Twilight" actress Kristin Stewart, 22, was reportedly unfaithful to her long-time boyfriend and co-star Robert Pattinson, 26. The awkward beauty had a quick fling with "Snow White And The Huntsman" director Rupert Sanders,41, a married father of two.

"She wasn't having an affair with Rupert. It was just a fleeting moment that shouldn't have happened," a source pleaded in her defense. "She never meant to hurt anyone. She's a good person who just made a bad choice."

"Kristen is absolutely devastated," said another source. "It was a mistake and a complete lapse in judgment."

Sanders team remained mum when contacted for a comment, Likewise, Stewart's reps didn't respond to the allegations.

US Weekly claims to have photographic evidence of  Stewart's steamy trysts with Sanders. "It seemed like they couldn't get enough," reported a photographer.

"He worships her," a source close to pattinson said. "He doesn't think there is another woman on the planet who is as beautiful and kind as her. He wants to be with her 24/7, he wants to marry her...as far as he is concerned, Kristen is his perfect match...Kristen is perfect to him. That's why he's always known that someday she would be his wife." 

Pattinson hasn't commented on his girlfriend's infidelity yet or should we say ex-girlfriend? Stay tuned!
