Nobody at the AMA's sang well, especially at the beginning of their songs. It wasnt there fault, if you actually watched it sober everyone had severe audio trouble, due to noise interference if you cant here yourself sing over the instruments, Celine Dion would have had trouble. Once Katy belted out her great voice she sounded great as always, and if you dont know what Youtube is, you better move out of your mommy's house little boy and grow a pair! You ignorant baboon, sorry I shouldnt have insulted baboons so bad.

Her SNL performance was just so-so. But every other performance I've seen her do has been god-awful, from the AMAs to GMA to Letterman. She's one of the very few that SHOULD lip-sync when she does shows like that, just to save the audience some serious pain and ear-bleeding.

katy perry is fine idk wtf any of yous is talking about

awesome song really but maby shes not so good at live performance. u cant say that she is have no talent,she got so many top hits recently
