2. Justin Bieber
In order to be as popular as Justin Bieber is, somebody has to actually admit to liking you. Yet it seems more and more like nobody wants to step up and claim ownership of their fanhood. Justin Bieber’s Instagram is a mirror to the world of ‘Bieber Fever’ and exudes the kind of self-importance that only pretentious teen pop stars can manage to convey. Full of selfies, rich kid toys, and celebrity cameos the Bieber Instagram feed is one to avoid.
