Katy Perry Performs "Firework" & "Peacock" / by

Yesterday Katy Perry did a special concert in New York at the Ed Sullivan Theater where she performed "Firework" and "fan favorite "Peacock". Check them out below.



Make sure you guys pay attention the the black back-up singer and how she messes up on the 2:15 mark in the "Firework" performance. Katy looked back like "which one of you bitches messing up my song"?! The camera went back to the girl and she was just smiling like everything was okay, knowing that she got fired right afterwards. Both performances were okay, Katy just need more practicing while single live becuase her voice is so shaky. Especially in the "Firework" performance, her voice was every where and it was not cool. But good effort.
