Anne Hathaway At Premiere Of 'One Day' Says She Mooned Co-Star On-Set

Even with the most professional actors, there's always bound to be some goofing around--especially when there's nudity involved.

Anne Hathaway and Jim Strugess hit the red carpet Monday night for their New York premiere of the epic love story, 'One Day,' and shared some pretty candid details.

While they were shooting the eye-brow raising skinny dipping scene, Hathaway decided to have a little fun and mooned co-star, Sturgess.

She was careful to avoid their film crew but missed the apartment building full of peeping toms who were, apparently, filming from their windows.
