Katy Perry bundled up as she left for Heathrow airport this morning in London, but it wasn’t cold enough to put the pop star in a icy mood, as she smiled warmly for the cameras while jumping into her car.

So what else is going on with Mrs. Russell Brand? At the BBC Radio 1 Teen Radio Awards in London last night Katy performed her new single “Firework”, and she began to cry as she took to the stage! Katy told the crowd, “I’m allowed to be emotional. Thank you so much for supporting me in this song because it means so much to me.”
