Evidently, Kristen Stewart and Robert Pattinson have hit a rough patch.
According to Us Weekly and People, Kristen Stewart has allegedly cheated on Robert Pattinson with her Snow White and the Hunstman director, Rupert Sanders. The two APPARENTLY had a "marathon makeout session." (Yikes.)
Said a source to People, "Kristen is absolutely devastated. It was a mistake and a complete lapse in judgement. 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."
The story gets even more messy when you learn that Rupert Sanders is 41 and married to model, 33-year-old Liberty Ross. They also have two kids, ages seven and five.
However, until Kristen Stewart or anyone else involved can confirm anything, we might as well take these "source"-heavy reports with a grain of salt. After all, at the Teen's Choice Awards, K-Stew and R-Patz seemed pretty happy to be there.
