Her hair looks a mess because her hairdresser left before doing her hair. One report says she fired him, he says he quit...so...?
She tried to put her hair extensions in herself, and wasn't very successful.

The best thing to come out of this is Leave Britney Alone and all the various reply videos. Don't click, kiddies and worker bees, bad language! However, I'm now a Chris Crocker addict. I think I spent an hour watching his Youtubes last night.
