Katy Perry's Interview mag cover: Would you recognize her?

Katy Perry is virtually unrecognizable on the cover of March's Interview magazine.

We have to admit that even we -- entertainment professionals -- thought we were looking at a vintage Elizabeth Hurley pic when we first saw the vampy version of Perry. The recently-divorced singer rocks a jewel-encrusted bustier, heavy eyeliner and a lush raven wig in a messy updo.

She's, in a word, simply stunning. Though we're pretty convinced there was at least a little photo retouching involved to give her those cheekbones.

Perry also bears more than a passing resemblance to Amy Winehouse, the late British singer who happened to be a close friend of ex Russell Brand's.

What do you think of Katy's drastically different look?
