Christina Aguilera gets down and 'dirrty' with an on-screen love interest in her first movie role.

The 29-year-old singer closes her eyes as shirtless Cam Gigandet showers her with kisses in a scene from forthcoming film Burlesque.

Other clips from the musical flick show the pop star leaving little to the imagination in a flesh-baring leather outfit and policewoman's hat.

Even co-star Cher appears scantily-clad, wearing a costume with a plunging neckline for one sexy performance.
