Sneak peek: Britney Spears targets paparazzi in her new video

In the clip the troubled pop star, who wears low rise jeans, a sequinned bra and tiny jacket, performs a loosely choreographed dance routine, while a group of Britney clones are hounded by photographers.

In the video, Spears sings: "I'm Miss American Dream since I was seventeen, don't matter if I step on the scene or shrink away to the Philippines.

"They still take pictures of my derriere in the magazine. You wanna a piece of me?"

She also complains that constant media attention means every day is "another drama".

To that end, Britney caused a media storm this week when she failed to turn to a scheduled deposition in her ongoing child custody dispute with former husband Kevin Federline earlier.

News media and paparazzi was waiting for the pop megastar to show up Wednesday morning at attorney Mark Vincent Kaplan's office.

But Kaplan, Federline's attorney, said he had been told that Spears was not coming, with friends claiming she was suffering from "high anxiety".

Kaplan said he was told Spears did not feel well and that she would give her court-ordered deposition at a later date.

Spears and Federline have been arguing for months over custody of their sons, two-year-old Sean Preston and one-year-old Jayden James.
