With the premiere date of the new Britney Spears MTV documentary getting closer we are getting some tasty sneak peeks at what goes on in that nasty-weaved head of hers. There’s a lot of dancing and weave tossin’ in these videos and if you can stand to listen to her empty-headed rambling, you can actually see a glimpse of the old Britney when she starts dancing.

Instead of telling us all what we really wanna know, like how high was she really the day she shaved her head or how many days did she actually stay awake at a time during that drug-fueled meltdown…..she decided to fill us in on what went wrong with Kevin Federline.

“I think I married for the wrong reasons,” she says. “Instead of following my heart and doing something that made me really happy, I just did it for the idea of everything.”
