Talk about shocking! A mere three nights ago, Kristen Stewart attended the Teen Choice Awards with boyfriend and Twilight co-star Robert Pattinson but, oh, what a difference a day (or two or three) makes!
Reports are breaking that K-Stew had a fling with Rupert Sanders. For anyone keeping score, Rupert directed her recent movie, Snow White and the Huntsman. And that's not all -- he's a married man! Rupert's wife, Liberty Ross, also starred in Snow White, and they have two children together.
None of their reps has commented so far, but a source told People Weekly, "She wasn't having an affair with Rupert. 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."
Another insider added, "Kristen is absolutely devastated. It was a mistake and a complete lapse in judgment. Robert worships her. 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."
So, what's going to become of Kristen and RPattz's relationship, one which became public in 2010? Weigh in below!
