Thanks to the release of her most recent album, Teenage Dream, we've been seeing lots of Katy Perry these days. And when it comes to her beauty stylings, she's no stranger to mixing things up. From a blue Bettie Page-style wig to holographic nails to a bouncy chin-length bob, this "California Gurl" is always turning heads. Her most recent look: various blue, pink, and purple highlights woven throughout her dark hair. Are you loving it?
