Katy Perry
looks incredible on the cover of the new Interview Magazine ... she just doesn't look anything like Katy Perry!

Thanks to some drastic hair and makeup, the singer looks more like Megan Fox or even a young Elizabeth Taylor than the same girl who sang "Teenage Dream."

Not that we're complaining ...

There's no denying Katy looks amazing, especially in contrast to the just-released photos of her from an upcoming episode of "Raising Hope" -- where she sports a curly red wig and facial hair!
