I just saw the big Britney Spears dance routine on the VMAs.
It appears to me that Ms. Spears has grown awfully bored with being a pop star.
Sure she can still wear the outfits (i.e. almost nothing) but her lip syncing was lazy (no one expects her to actually sing) and the dancing which usually got the most energy was half-assed.
Oh, and the song wasn't very catchy either, some cookie-cutter club tune expressing Ms. Spears needs. "Gimme, gimme more!" begged Spears unconvincingly, it is presumably the first radio salvo from her upcoming album.
