Which Celebrity Has the Best Body Double? [PHOTOS]

Jennifer Aniston and her double on the set of We're the Millers

Even Jennifer Aniston Uses One!

Thanks to at least six workouts a week (PLUS yoga sessions), Jennifer Aniston has a body nearly every man wants and every woman covets. But would you believe even she uses a body double when it comes to some of her more risqué movie scenes? A double for Aniston was recently spotted running around in her underwear on the set of Aniston's new movie, We're the Millers.

She's not the only one relying on hired help. Years ago, it was famously revealed that the image of Julia Roberts in all those ads for Pretty Woman weren't all her -- they were of her head superimposed on a model's body.

And it isn't just the women who use them. Oftentimes, even the manliest actors use a double to film scenes in which they could potentially get hurt. Can't have anything happen to that million-dollar mug, after all.
