Rumors are swirling that Twilight star Kristin Stewart cheated on her vampire co-star Robert Pattinson.

Who is the other man? Rupert Sanders, director of Snow White and the Huntsman, which she also stars in.

Sanders is best known for directing numerous TV advertisements. His adaptation of the Disney classic was the first feature film that Sanders reportedly directed in early June 2012.

Since news broke, the scandal has made headlines across the globe. Pictures of their romp spread across the Internet just days after she attended the Teen Choice Awards with Pattinson. US Weekly featured a photo of Sanders embracing the young star.

Not only has Stewart, 22, been in a relationship with 26-year-old Pattinson for over a year, her alleged lover is married with two children. Making the alleged fling even more suspicious, days before it went public, the 41-year-old’s wife, Liberty Ross, 33, reportedly posted one word on Twitter, “Wow,” before canceling her account altogether.

At the moment, reps for both Sanders and Steward have not commented on the matter though a source chalked it up to misjudgement and not a full-fledged affair.

“Kristen is absolutely devastated,”  People magazine quoted an anonymous source as saying. “It was a mistake and a complete lapse in judgment.”

Pattinson and Stewart seemed to be going strong in recent years since they first met on the set of Twilight and rumors of a budding romantic relationship off the set began swirling. The two didn’t go public until months later but have since become the cookie-cutter successful Hollywood relationship, until now.

What do you think of the alleged affair?
