Has Kristen Stewart been busted cheating on boyfriend Robert Pattinson?
Reports flooding out of the US suggest that's the case.
People is reporting the starlet cheated with Snow White and the Huntsman director - who's married with two children - Rupert Sanders.
Sanders' wife, who also appeared in Snow White and the Hunstman, posted a one word tweet - "WOW" - earlier today before deleting her account.
"Kristen is absolutely devastated," People quote a source as saying. "It was a mistake and a complete lapse in judgment...
"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."
