US Weekly reports that the actress was paparazzi’d in a few “steamy rendezvous” photos with her Snow White and the Huntsman director, Rupert Sanders.
A source tells People: “Kristen is absolutely devastated. It was a mistake and a complete lapse in judgment.” The source adds, “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.”
A rep for Sanders, who is married and has two children, could not be reached for comment. Stewart’s rep has had no comments.
