Hold on to your seats, “Twilight” fans. According to a report from People magazine, Kristen Stewart cheated on long-time boyfriend Robert Pattinson with her “Snow White and the Huntsman” director Rupert Sanders.
The bombshell came in an anonymously-sourced item posted Tuesday (July 24) to the magazine’s website.
“Kristen is absolutely devastated,” a source tells People. “It was a mistake and a complete lapse in judgment.”
“She wasn’t having an affair with Rupert,” adds the source. “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.”
Neither Sanders nor Stewart have commented on the report. Obviously.
Stewart and Pattinson recently appeared together at Comic-Con to hype the final installment of the “Twilight” saga, “Breaking Dawn – Part 2.”
UPDATE: Us Weekly posted a copy of their new cover, which includes a purported picture of Stewart with Sanders and details on how the alleged liaison unfolded. Us claims the pair was caught together — at least on camera — on July 17 in a “series of steamy rendezvous.”
Us also adds the detail that Sanders is engaged to model Liberty Ross, with whom he has two young children.
