Britney Spears' press and pap payback in new promo

Britney Spears shows off her comedic talents in her video for new single I Wanna Go, by swearing at reporters, beating up paparazzi and flashing at a cop.

The pop superstar is preparing to launch her third single off her latest album Femme Fatale, and has opted for a satirical take on her life for the track's promo.

The video kicks off with a mock press conference, in which Spears claims she's expecting quintuplets with Brad Pitt, calls a journalist fat, and says "f**k you" to individual reporters.

She then makes her way down a busy street and stuns passers-by by slapping one man on the backside before exposing her breasts to a police officer, who then saucily frisks the star.

The Toxic hitmaker also takes aim at real-life paparazzi who follow her daily, by whipping them with a microphone and revealing them to be Terminator-style cyborgs.
