AMAZING! Love this girl!

Her live singing is pretty good!

great performance!

Amazing vocals. Love it.

Wow. I for one am amazed. It was fantastic!

That was awesome!

Amazing vocals? She definitely CANNOT sing...HOWEVER, I was entertained. Great vocals just isn't her thing.

How can you judge vocals based on this performance? She doesn't even try to sound good, it's just a fun song.

Yeah. I said Amazing Vocals because I heard Mannequin live.

yeah, she sings amazing!

Her vocals on this performance were better than her previous ones of this live

As a performance, I liked her Spike TV one better. I loved when she screamed INNOCENT! on that one, haha.

This was good though, nothing wrong with her vocals like other people claim. She just kinda bopped around like she was afraid of being too sexual though, lol.

katy perry :melryan: love her!

Terrible, she sucks live!

I like it...ooo ooo wooo...

Amazing peformance. She looks hot too.

Katy <3

It was just okay. I still love Katy though.

Her vocal delivery reminds me of Nicole Scherzinger..trying too hard while not trying enough.
