Kristen Stewart cheated on Robert Pattinson with the director of "Snow White And The Huntsman," who is married and has two children, according to reports.
Stewart, 22, and Rupert Sanders, 41, were caught by a photographer last week at a passionate date.
Stewart is "devastated" for what she did, according to People Magazine.
"Kristen is absolutely devastated," a source told People. "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," the source added. "She never meant to hurt anyone. She's a good person who just made a bad choice."
Us Weekly says the affair occurred lat Tuesday and that the magazine will publish exclusive photographic evidence on Friday on its new issue.
"It seemed like they couldn't get enough," one photographer told Us Weekly.
Pattinson and Stewart made the latest public appearance together at the Comic-Con convention where they discussed the movie "Breaking Dawn Part 2."
Both of them were laughing and seemed happy making jokes about their romantic scenes in the film.
Rupert is married to supermodel Liberty Ross and has two children, a 5-year-old and a 7-year-old.
"Snow White and the Huntsman" was released on June 1. According to the Internet Movie Data Base, it was his first blockbuster film.
