Katy Perry decided to go clubbing in London last night. Looks like she started out demure with the silver-gray sweater but lost it at some time during the evening. This doesn’t fit with the “image change” she reportedly wants, but I don’t know if she truly wants one or not (although her new music video seems to be a start in that direction).

I have to say, Katy still looks unhappy, but I don’t know if that’s because she’s still dealing with her split from Russell Brand or because of the paparazzi presence. She can’t hide anywhere, especially with that blue hair!
