Perfection,

I would have thought this would have been posted but I can't find it anywhere.

Thx but GOING POP rapes my computer and I'm never able to pull up a link

^ OMFG!!! The same **** happens to me!!

Found one

WTF??? she didnt sing a ****!


not able to hit one high note!!! and definitely the song is nothing live

This is not a good performance. Katy is capable of much better. But the song actually works very well live IMO.

I PAUSED CELINE FOR THAT?!?

i dont think i have seen you give one nice comment to someone other than Rihanna.
The performance was great, no need to drag her.

She definitely improved, but I did cringe at some parts.

I LOVE GAGA, BEYONCE, PINK and JUSTIN and I enjoy Katy Perry. But this performance was crap. Even more knowing that is was PRETAPED

Her voice is dreadful. She didn't even attempt the high note before the last chorus and sounded like a barking seal half the time. Very disappointing for a Katy stan but at least it will help the song climb the charts.

Bad performance. Made me like the song less.

THANK YOU! Im not the only one then

I LOVE Katy, but her live vocals have yet to improve. She's great acoustic, standing still with a guitar (check Brick By Brick from her Unplugged). However anything else just turns into a mess. Even Ke$ha gives more consistent vocals than this.

This performance wasn't that good.. I prefer studio version

her voice got better, but am sure she can do better than that

Great performance

she still cant sing live

but she makes hot videos

I luvvv Katy, but gonna admit her vocal isn't good at all here. She had improved alot live dis era, check out her live performance in singfest, she killed da mini concert

This was so boring.
