Katy Perry turns 27 today, and she only gets better with age. She has always been a head turner, whether it’s her outrageous stage outfits or her even more outrageous physique. One thing that has changed numerous times throughout her career, however, is her hair. Mrs. Brand likes to change it up whenever she can, starting out her career with jet-black locks (even though she’s a natural blond), going to electric blue (possibly inspired by her character Smurfette?) and most recently turning it a shocking pink. Check out our gallery of Katy’s 20 hottest hairstyles (and wigs, we’re not gonna lie), spanning her career as one of pop’s most colorful artists.
