Did he cut it or didn’t he? It’s a question that Justin Bieber fans have been debating the past few months, as the singer’s signature mop-top hairstyle has crept ever shorter, knocking off a millimeter here and a millimeter there. But when Justin turned out in N.Y.C. this weekend for the launch of his memoir First Step 2 Forever: My Story, it seemed that all those micro-trims had taken his coif over the tipping point–giving his overall look a shorter, neater appearance. And while we’re intrigued by how the choppier styling carries him from ‘tween to teen dream, we can’t help but wonder whether he still has the goods to pull off his famous hair swoosh. Tell us: Do you think Justin should keep cropping his hair, or stay true to his signature shag? ?
