It's crazy to think that Justin Bieber is already 19-years-old. It seems like yesterday that he was the prepubescent Internet sensation. But now, Bieber is grown, and into his fashion thing. The singer celebrated his 19th birthday on Friday in London, and chose to tame down his style, a little bit. Bieber rocked his usual leather pants and such, but broke out a Christian Louboutin Syd Leopard backpack. Normally people don't bring out a backpack for a night on the town, but when it's this high-end, you tend to get a pass. What do you think of the Biebs' look?
