Kristen Stewart is sporting a cast on her arm after injuring herself while filming The Twilight Saga: Breaking Dawn, according to a U.K. report.

The actress flew in to Los Angeles earlier this week and was snapped at the airport with her left hand in bandages.

Rumors have been rife about the cause of Stewart's injury, and Britain's The People newspaper claims the star was hurt while shooting a scene for the latest installment of the Twilight franchise.

A spokesperson for Stewart had not commented on the injury as WENN went to press.
