0 Jennifer Aniston In 'Horrible Bosses'

Jennifer Aniston has spent nearly two decades playing the good girl, unlucky in love and eventually some guy's sweetheart. That's not exactly the character description in this new film.

Aniston stars in the ensemble comedy "Horrible Bosses," playing Charlie Day's boss: an extremely sexually aggressive dentist. Whom he wants to kill.

She's one of three hilariously awful bosses, alongside Colin Farrell and Kevin Spacey, that drive Day, Jason Sudeikis and Jason Bateman to murder. Or, their best attempt at it.

The film is drawing buzz for both its comedy, and the chance at a rare glimpse of Aniston skin; she filmed a topless scene, which may or may not get used.

After years of posing naked -- but playfully concealing her breasts -- Jennifer Aniston, 42, may finally flash her assets in the raunchy comedy Horrible Bosses.

"She shot a topless scene, but produces aren't sure if they'll use it," a production source tells the new issue(on stands now). "They filmed it two ways I one, you see Jen's face and boobs in the same shot. In another, the audience might think it's a body double."

Still, the source insists the famously fit star -- who plays a dentist who sexually harasses a male employee (Charlie Day) -- had no problem doing nudity. "She knows she can't show off her boobs forever, so she's going out with a bang!"

Still, a second source tells Us, "Jennifer did not shoot a topless scene. She may appear nude, but you do not see Jennifer topless."

The naked truth won't be revealed until the flick opens July 8, but in the meantime, the movie's posters will titillate too. "She told marketing to push the envelope on this one and not play it safe," a source says, noting that one will feature Aniston with a banana in her mouth. "The studio is playing up her sexuality, and she's all for it!"
