30 photos that show how Katy Perry's beauty looks have evolved

The video for her first hit, "I Kissed a Girl," cemented her as a glamorous pop star in the making, with a knack for a classic Hollywood pin-up aesthetic. By the time she moved on to the candy-coated brightness of the "Teenage Dream" era, we knew that Perry was here to stay — and that she'd be serving some iconic looks along the way.

We've since seen the singer change her hair more times than we can count, and she's also made some bold choices with her makeup. Whether it's the bright blue wig and colorful makeup of her "California Gurls" days or the super-short pixie cut she's currently rocking on tour, Perry always owns whatever look she's going for.
