[TheBeatleManiac101]

That's a cool ass cape

[zombillymays]

My little brother, who was probably 8 at the time said of this performance, "Who is this? She's AWFUL!" She can't sing. Glad people with actual talent like Adele are still getting played.

[SuperMrKazu]

@zombillymays well...tell your little brother to hit puberty first and then he can talk bout' who has talent or not !! Or..he can go straight to hell..that way , his fcking mouth can shut forever !!

[KnowYourEnemys]

@SuperMrKazu bitch..

[fanofwhatever1027]

@zombillymays I agree she's horrible but i saw her in concert last night and she's actually not bad

[marcellisrobinson]

Katy Perry: A very good looking girl with little talent. Just another midriff who got very lucky in show business. Pretty face, nice boobs, and a hard working publicity machine behind her. In this day and age, why shouldn't she be famous?

[minovioesmilo]

KATY PERRY THE NEW QUEEN OF POP!

[paezperry]

shake the glitter!

[melirose89]

whats funny is that Adam was dressed like Jailhouse Rock Elvis that day. I think it was purely coincidental though. Adam said he was really really surprised when it happened. unfortunately they blurred out the Adam Lambert name on her Elvis cape on Itunes, thanks for this!

[AdamLambert9711]

GIVE ME THAT MOTHER FUCKING CAPE RIGHT NOW BITCH!!!!!!!

[CycloneGU]

I thought Adam won, actually...but he did make it to the finals. He's been more notorious in the media and in retrospect probably should have won, as he currently has the better career I think. Just like Clay Aiken. Quite unlike Carrie Underwood, a rare winner who went on to have an explosive career.
