Britney has been 'hard at work' shooting her new video Piece of Me, which apparently involves a bunch of body doubles. Having a bunch of look-a-likes makes it a lot easier for her to fall asleep in the corner under a bunch of coats without anyone noticing. I'm pretty sure these are professional actors, because it would take a lot of work for the average person to actually imitate Britney Spears. Can you just imagine these girls getting into character on their way to the set - strapping the kids to the top of the car, running all those stop signs, having sex with random people on the way. That stuff takes skill.
