Actress Jennifer Aniston has revealed that her Scottish co-star Gerard Butler used to flash his butt on the sets of their new movie "The Bounty Hunter". Aniston said the actor was a practical joker while shooting the movie and used to amuse the crew by baring his behind, reports accesshollywood.com. Speaking in an interview with Gerard, she said: "You would moon the crew walking by the wardrobe trailer. That's how close our family got," said Aniston.
