ooops she did it again...but why?

Im sure everyone by now has either seen or heard the story of Britney Spear's performance of the VMAs. If not check out the clip below. Why people did she get up there and make a fool of herself? I know my mom always told me, "If you don't have something nice to say don't say it at all," but she was a super hott mess! I mean even the audience were wondering what in the world she was doing up there. She should bot have come to the award show so unprepared. I think that it is a good thing that people are making fun of her because maybe this will show her that her actions that led up to this disasterious performance were to say the least.. stupid.When will she learn that drinking and doing all that excessive parting will not bring her career back to the level it once was.Damn that Kevin Federline!! if she would have just stuck with JT maybe she wouldn't be making such a complete fool of herself. She could probably learn a lesson from him on how to bring sexy back.And it's not with a sparklely bra and panties.
