Katy Perry @ Formula 1 2012 in Singapore

Medley of performances by Katy Perry at Formula 1 Race in Singapore 2012. Sorry for the very shaky videos. I mean who can contain their excitement and not party when you see Katy? Most of the voices/screams are all by the people around me! HAHAHA if you can't stand the shaky ones, just move all the way back to Firework, i think that's the most stable one :) Follow me on twitter @vienena
