It was cute

It's so sad to think she can actually put on a good performance, but she always performs like **** on large televised events

DEATH at any of you thinking Katy is a "powerhouse vocalist". I hope you guys were just kidding.

Welcome to ATRL newbie. People are just kidding

her vocals have gotten so much better though!!

wow amazing performance!

I know she isn't the best with the live vocals but she sounded so good at this gig whatever it was, go to the youtube page that uploaded this video and check the others, she slayed!

Hey, take it up with Emmy Award and 14-time People Choice Award winner Ellen Degeneres, who gave her that title!

This was beautiful. Consistent vocals, it sounds like a studio version.

Powerhouse Vocal ICON of our GENERATION more like it.
