Justin Bieber is mobbed by so-called 'Beliebers' as he checks out of an upscale South Beach hotel late Friday on the way to the airport. The 19-year-old celebrity has been inundated by media attention over his recent run-in with the law. On Thursday, the Canadian singer was arrested on a drunk driving charge after police caught him drag racing on a Miami thoroughfare in a rented Lamborghini. He was later set free on bail. There was no immediate word on where he was headed after Miami Beach.
