It was a one-time mistake. That’s the line Kristen Stewart is hoping will keep Robert Pattinson from leaving her, although early indications don’t bode very well for the future of Robsten.
But is that claim even valid? Did Stewart really just make out with Rupert Sanders for a few fleeting moments? Or was this affair far more drawn out and calculating?

Rupert Sanders likes what he sees at the premiere of Snow White and the Huntsman.
Relatives of the Snow White and the Huntsman director say it’s the latter. They cite a photo of Sanders and Stewart in Berlin on May 15 as evidence, with Sanders’ brother-in-law telling People UK of the cheating:
“It was from the last half of filming and all through post-production, clear into last week.”
