Worst performance ever.

Why the hell does she have to do a medley? Like, what the ****? Is her management keeping up with "NMT" & "WooHoo" chart performance? That was a waste.

Katy >>>>>>>>

Standing ovation. The entire audience singing along. #1 hit. Bye.

great performance of her

You mad

I love Zac Efron.

Did Zac Efron just admit something when he said suck it?

OMG!! Xtina was amazing!!

Zack G. won!!!

Still think he should have gotten an Oscar Nod for that movie.

sooo does everyone thinks that new moon would win best movie???

So everybody is doing this, I will too.

Christina Aguilera's performance >>>>>>>> Katy Perry's performance

No comparison at all.

ALD crashed

now I need the viedo on youtube hahaaa

at this moment in time, yes....

I'm hoping for a miracle.But I aint counting it .

OMG

BOTH PERFORMANCES WERE AMAZING AND TOTALLY DIFFERENT SO THERE IS NO REASON TO COMPARE

I missed it God dammit. I hope it's up on youtube sometime soon.

Nope.

Boston looking like they are going to win Game 2

Is the Hangover nominated or Harry Potter?
Those are more likely to win imo.

I thought both Katy and Christina performance were OK, Noting Special either one of them own the other. They were stiff as hell and look very uncomfortable.

Tom Cruise>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Those Bishes FACT!
