Britney Spears on the set of her last video

Britney Spears is shooting a new music video for her single "Piece of Me" today in Hollywood. If the shoot is anywhere near as successful as last time (disturbing pics below), expect hours of downtown and a pissed off crew. Regarding today's video, Us Weekly says:

[A source] says that in the video, Brit and her dancers enter a club in matching wigs and trench coats in order to sneak Spears in. Once in the club and without her disguise, the pop star is followed by the paparazzi regardless.

A set source tells Us that since Spears, 25, has a scheduled visit with sons Sean Preston, 2, and Jayden James, 1, on Tuesday, she will only be available to film for two hours, between noon and 2 p.m. During that time she will shoot scenes where she dances on a bar and runs down a staircase. There will be 15 extras, as well as a body double for Brit. (Source)

A body double for Britney? I thought Drew Carey is hosting The Price is Right? How did he find the time? BTW, the production crew better make sure the bar she's dancing on is reinforced--load bearing beams often crumple at 750 pounds. And how does she possibly think she can film an entire video in only two hours? I hear the special effects people at Industrial Light & Magic need at least two days just to get her to look human.
