Transformation

"I love pinups," Katy Perry has told InStyle. "I've taken a lot of direction from those girls in cute little outfits caught in flirtatious situations—with a dog leash tangled around their legs and their skirts blowing up." For the multi-platinum singer this means flawless cat eyes, Vargas girl lips and candy-hued locks. The dress-up queen has also posed as Queen's mustachioed Freddie Mercury, a denizen of Candy Land (in her "California Gurls" video) and as a variety of high school archetypes (at last year's Teen Choice Awards), it's safe to say we can expect some exciting new looks from the Teenage Dream. "We have a great relationship," her colorist Rita Hazan told us. "Katy is the ideal client because she loves to be creative and unpredictable."

As a freshman at Dos Pueblos High School in Goleta, CA, the blond (!) Perry idolized Freddie Mercury.
