WHERE'S THE "ZAZAZOO"?

Awww, BritBrit!!! I'm so glad to see her back in shape and a bit more sane but I must say that something is different about her. Now I'm sure one can't go around beating cars in with umbrellas and shaving their own heads without some residual abnormalities but it seems like her spirit is gone. Maybe she's not full out because its just rehearsal but I'd assume she would be since its being used as promo for the tour and her Candie's venture... She's executing the moves at "Old Britney's" level but her face lacks energy; its like she's just going through the motions, you know? Well, thank God for dancers 'cause they make the show for most of these pop artists anyway...
