This is all getting a bit sad really. Britney is continuing her performances, but if anything they're getting worse, which judging by the pictures of the first performance, would have to mean that they're now about the same quality as the first grade Christmas recital.
Call me crazy, but I don't think that prancing around in hideous clothing and lip syncing to old songs is really performing in the 'I paid over a hundred dollars for this ticket sense.' To add insult to injury she was apparently spotted chewing gum during the songs.
Maybe Britney just really has lost her mind. Chewing gum during your act is fine if you're a ventriloquist, but otherwise it really has no place. Sane people know this but Britney probably thinks that she's playing for the Queen of the Universe or something and that the cowboy boots she's always wearing have magical powers.
This whole thing gets even sadder when you realize that Britney actually put off some of these performances because she felt she wasn't ready for them. I suppose she hadn't got her chewing in sync with the music as yet. Good to see she got that sorted.
