You want a piece of Britney? You definitely could have gotten one at Planet Hollywood last Friday, as the pop star lost a large chunk of hair while performing her hit "Do Something." Well, it wasn't her actual hair, but it hasn't been for quite some time...

A clump of Brit's extensions fell out and got stuck to her butt for a second or so, and they then fell to the floor when she zipped around on the stage. In fact, it seems like she didn't even notice the wardrobe malfunction, as she carried on her performance without a hitch. Britney recently renewed her contract with the venue through 2017, so perhaps they could invest in a better weave for the next leg of the residency?

On the plus side, at least she didn't pull a Madonna and fall on her butt!
