Think you've seen your favorite stars in the buff? Think again.
Brooke showed off quite the curvy backside for a 14-year-old while skinny dipping in 1980's "Blue Lagoon," but the young actress actually had a body double do the deed.
The Spanish beauty was pregnant while filming "Pirates of the Caribbean 4," but luckily she had just as stunning little sis Monica to fill in. Pays to have good genes!
Fans may think they got a rare glimpse of Catherine Zeta-Jones in the buff in "Traffic" (2000), but it was actually a body double.
Check out which other stars let someone else step in to go bare.
There was some confusion over whose backside was shown in a thong in 2011's "Your Highness," but Natalie says, "There's one shot that's me and the shot of her diving into the water is a body double, because I didn't wanna go in the water - it was really, really cold."
For the lingerie scene in "We're the Millers" another blonde stepped in with almost identical hair to Jen Aniston, but if you look closely, you can tell she's more blonde than the star.

It was first reported that Kate asked for a body double for a shower scene in "Whiteout" where the camera was going to pan over her derriere. But the studio said it was standard procedure.
"The claims appearing on the Internet today that Kate Beckinsale requested a body double for filming 'Whiteout' are absolutely untrue," the studio said. "As is standard practice on many movies, a body double was hired for several scenes by the production and not at the request of Kate Beckinsale."

In "Domino" Keira Knightley used a body double for the lap-dancing scene. But it wasn't because she was feeling modest.
"It's definitely a body double, I don't have that body," explains the star. "What a bum! I wish I had that bum... It was fantastic."
Of course the actress isn't the only star who takes a back seat when it comes to showing skin.

Jessica Alba has always been outspoken about not appearing nude in films, so it left many wondering whether or not she used a body double to film the crazy scenes in "The Killer Inside Me" (2010).
That same year it looked like she also went nude for "Machete," but her rep set the record straight.
“Jessica has been steadfast in her resolve not to appear nude in films from the beginning of her career," her rep explains. So instead, the nude look was digitally created.
"The decision to digitally remove the underwear from the shower scene in 'Machete' was one she and [director] Robert Rodriguez made together, which would serve his vision for the film, as well as honor her personal convictions regarding nudity," she said.
Okay okay! Relax!
The "Wedding Crashers" star had a body double for her topless scenes.
"I feel like if you have a female comic character and then you see her nipples, then she is no longer funny, which is clearly wrong, but that was my theory, and that's why I didn't want to do it," she said.
Wilson had a butt double in "You, Me and Dupree."
"The director made that decision not to use my butt," he said. "I don't know how to interpret that."
Owen wasn't the only Wilson brother to use a butt double... Luke hand-picked his stand-in for "My Super Ex-Girlfriend."
"I thought it might be a good time to sit on the bench for that scene and let some other kind of more athletic guy take over there," he said.
The "Up in the Air" star had just given birth before filming the award-winning movie, so when it came time to strip down for her steamy scenes with George Clooney, the actress had to call in some help.
"The breast milk down both sides -- it would have been inappropriate," she told Entertainment Weekly.
A scene in "Immortals" called for a shot of the gorgeous actress' backside, but she was relieved when the filmmakers chose to go with a double.
“It was a butt double," she told E! Online. "I’m relieved I don’t have to deal with that issue."
Her flick, "Friends with Benefits" may show a lot of skin, but not all of it is hers, explains the gorgeous brunette.
"I showed side boob and I figured I can't just give everything all away at once," she says. "I gotta let it all out in little pieces here and there."
So instead of stripping down when it came time to show the world her derrière, Mila stepped back and helped find a double that could stand in for her.
'These lovely women had to show us their derrière and we chose the one that resembled my body the most without looking like it is fake," she explains.
Meryl's nude body double in "Death Becomes Her" (1992) stepped away from Meryl's naked shadow to become an actress.
Catherine Bell was said body double, and went on to star in "JAG" and "The Last Man Standing."
An interesting way to break into showbiz.
Geena Davis had a body double for "Thelma & Louise" ... but didn't use her.
Director Ridley Scott hired a body double for the steamy sex scenes between Geena Davis and Brad Pitt, but stand-in Julie Strain says that she was actually never put to work.
"Geena started feeling comfortable with the love scenes," the former Penthouse Pet of the Year admits. "So I was paid but never used!"
Fans may think that they are finally getting a glimpse of Olivia Wilde's bits in "The Change-Up," but she recently attributed the "nip slip" to technology.
“I wasn’t actually naked," she told Jimmy Kimmel. "But now I appear naked. They CGI’d me naked.”
Ain't technology grand?
That wasn't Kevin Costner in the buff in the waterfall scene in 1991's "Robin Hood: Prince of Thieves."
It was a body double.
The curvy derriere in "Wanted" does not seem like it belongs to stick thin Angelina Jolie. The tattoos were airbrushed, so why not the backside?
Julia Roberts breakout role in "Pretty Woman" was really only partly her own. She had a body double stand in for several scenes where she appears curvier.
The most deceiving of all is perhaps the movie poster - where she's in a pink top standing next to Richard Gere. Yea, that's apparently not her either.
Lindsay Lohan was not the nude star in the pool scene in "Machete." Director Robert Rodriguez confirmed that those scenes were shot before the actress signed on to do the film.
So her body double was in the movie before she was. And the way her career is going, she may soon be doubling for the double.
