Kristen Stewart Cheated On Robert Pattinson

July 25th, 2012 9:32am EDT

ks Amongst rumors that ‘happy’ couple Kristen Stewart and Robert Pattinson were recently looking for engagement rings, a new scandal has rocked their perfect vampire relationship.

Apparently, Kristen was caught in a heavy make out session with her married director of Snow White and the Huntsman, Rupert Sanders. The two reportedly got carried away and it meant nothing to them...we're pretty sure it meant something to Rupert's wife and the mother of his two children, Liberty Ross and to Miss Stewart's man, Robert. Shame on them!
