Katy Perry is one of our favorites to watch. Since bursting on the scene — and on all of our playlists — with "I Kissed a Girl," we knew Katy Perry wasn't just about the music. The pop star is a performer in every sense of the word. Her girlie-girl-meets-sex-kitten style has captivated us from red carpet award shows to premieres, parties, and even her playful street style. She marries her pop vocals with cool, retro-inspired pinup costumes to take the stage, then outfits something more glamorous and entirely unexpected for red carpet appearances — for starters, you may remember her light-up gown at the Met Gala last year? Since today is the lovely Katy's 27th birthday, we're celebrating with a look at some of her most memorable style moments. Click through for the ultra-outrageous looks we love and join us in wishing Russell Brand's better half a very happy birthday.
