His real accounts name is Justin Drew Bieber
Justin bieber has two facebook accounts one for fans and a personal for his friends that he actually knows his personal facebook name changes often so there really is no use in looking for him if his profile was public there would billions of people sending him request and messages and he wouldnt have time to connect with his real family and friends sometimes you need time for yourself you know? And no I can't give you his facebook profile name that wouldnt be fair. Not that he dosent care for his fans because he really does there is just too many of you to get to know you understand? Does this answer any of your questions?
