[greigorypparker]

really chrisglopez? the only signature she has is altering her voice on every song she has ever done .......... she is horrible

[RainbowCuppercake]

playback is 0:33-0:57 and 1:07-4:06, but she kind of sings in the background in 2:38-3:27.

live is 0:57-1:06

love ya brit brit

[konrad52292]

amazzinngggggggggg

[chrisglopez]

the best dancer/performer of our generation!!! nobody can move like her... madonna is a good dancer but doesnt have that signature move... britney does... when she even walks you can see it... there are only a few who have that signature they can call their own elvis, MJ, and brit brit!

[christian13400]

@chrisglopez no mj is but hes dead which suckes bc he was a bad ass dancer

[MDproductionSS]

@chrisglopez but she doesn't move like that anymore.. she used to walk differently, you know, like with her hips moving a little more than normally walking

[TomatoBasil23]

@chrisglopez usher

[elchami743]

@chrisglopez I just see on this video that her moves are very rigid, stiff, tough. Not her best performance, i've seen better ones of her.

[brookadro]

@chrisglopez Excuseme? What about Shakira?

[DollarBill26]

@chrisglopez Ciara and Chris Brown dance 10 times better than britney

[DollarBill26]

@chrisglopez And Janet

[arthurw13]

[CelebrityProfit]

[chr1s524]

Part live, part pre-recorded imo.

[Ervideos1]

[stevearinososexy]

[DantBelmont]

[amazon455]

This is the playback big time! Sorry, don't wanna disappoint you but this is NOT LIVE! This song she recorded AGAIN probably just for this one performance. They do that all the time.

[LILPOPSTAR89]
