HQ Hollywood Celebrity Paparazzi Pictures

Troubled American pop singer Britney Spears will wow fans at Madonna's upcoming concerts by snarling her famous "It's Britney, bitch" catchphrase on a huge screen, while prowling around an elevator like a caged beast.

Spears has shot her movie segment for pal Madonna Ciccone's "Sweet and Sticky" tour at a studio in West Hollywood and now details of the short film are leaking out.

Bitney, wearing a grey hooded sweatshirt, paces back and forth in an elevator as cameras catch her kicking and punching the walls. As Madonna fans ask themselves who the angry hooded woman is, Spears pulls her hood down and delivers her catchphrase into the camera.

Pretty nice Britney, u indeed are a B*t*h!!!! (Ooopss..)
