Maybe out of shape (but still hot in my books) and uninterested in her performance (but for many it is enough that it is she who is on stage) but her song (not particularly inventive) is catchy and will indeed shake the dancefloors throughout the world. I predict her new album will sell big, and her MTV VMA appearance (unprofessional as it was) was enough to get it started. Britney is certainly a trainwreck with money.
