Christina Aguilera Shows Off Sultry Bob Haircut With Blunt Bangs. Christina may have her own style, but she knows how to glam it up for the red carpet. She showed up at the 2012 American Music Awards wearing a gorgeous purple hued ombre colored gown and a brand new hairstyle. 2012 has truly been quite the year for Christina and throughout many hair changes from pink dipped ends, to purple, and even red, it looks like she’s currently settling on a simple approach with her new shoulder length bob and blunt bangs haircut. Christina is of course beautiful with whatever hairstyle she chooses, but how amazing does she look with a simple blonde hair color and blunt bangs. I hope she decided to keep this look for awhile. See her new look below.
