Katy Perry turns up the sexy dial.

Katy Perry is almost un-recognisable on the front cover of Interview Magazine.

Katy seems to have channeled Amy Winehouse for this cover shot. What do you think of it?

Katy Perry just the other day at the Elton John Oscars party. Love the frock, but i’m over that damn blue hair. This gown would have looked so much better with her jet black hair.
