Jennifer Aniston may appear topless in her new movie.

The former 'Friends' actress has reportedly shot raunchy scenes for comedy 'Horrible Bosses' in which her breasts are on show but producers are still undecided as to whether to include them in the final cut.

A source told "She shot a topless scene, but producers aren't sure if they'll use it. They filmed it two ways in one, you see Jen's face and boobs in the same shot. In another, the audience might think it's a body double."

Insiders claim 42-year-old Jennifer - who plays a dentist who sexually harasses a male employee - was keen to do the topless scenes.

One said: "She knows she can't show off her boobs forever, so she's going out with a bang!"

Jennifer - who is famed for her straight-laced image - wants to play up to her "sexuality" so the film's posters will also be quite racy.

A source said: "She told marketing to push the envelope on this one and not play it safe. The studio is playing up her sexuality, and she's all for it!"
