Justin Timberlake Injured Leg On Film Set

Justin Timberlake’s blossoming acting career is starting to “rock his body” – – literally.

The Grammy/Emmy winner, who’s receiving rave reviews and Oscar buzz for his performance in David Fincher’s Facebook drama The Social Network, suffered an injury to the leg on the Los Angeles set of his upcoming science-fiction thriller Now this week.

The accident happened while Justin was performing a stunt for the new movie, which co-stars Mean Girls actress Amanda Seyfried.

“Justin Timberlake sustained a muscle injury to his calf on the set of Andrew Niccol’s thriller ‘Now,’” a rep for Fox — the studio behind the film — said Friday. “Production has taken a brief hiatus and will resume shortly.”
