Justin Bieber continues to rock other hairstyles after retiring the famed "swoop" 'do for a more adult look. He probably wants to be taken more seriously, and as a proven master of the swag, he deserves it. On Saturday at the NRJ Music Awards, Bieber hopped out of his time machine sporting a mature, slicked back '50s inspired haircut and a baby blue MCM motorcycle jacket (custom made by Taz Arnold). No one would have thought Bieber's hair styled like a character from The Outsiders would work for him, but he's looking like less of a teenie bopper, and more like a sharp dressed man. Nice one, Biebs. [MTV Style]
