Britney's Role In 'Goldmember'

Britney Spears uses her breasts to fight off spoof spy Austin Powers in new Mike Myers comedy flick "Goldmember."

The singer makes a cameo appearance as herself in the third installment of the movie series. And studio sources have revealed that in one funny scene, Britney attacks randy secret agent Austin - with her bulging bosom.

Austin - played by Myers - wanders onto the set of one of Britney's music video's and discovers she is really a deadly "Femme Bot" robot.

In the script, Britney even jokes about real-life rumours she has had a breast enlargement, quipping, "It's true, my breasts have been enhanced." Her nipples then open up to reveal machine guns, which she fires at Myers' character.

Britney isn't the only star to make cameo appearances in Goldmember - which hits cinema screens next month.

Tom Cruise, Danny DeVito, Kevin Spacey, Ozzy Osbourne and Gwyneth Paltrow also star as themselves.
