It's understandable that certain celebrities like to keep their distance from us mere mortals, but some take it too far. While many A-listers like to give their fans a tiny bit of satisfaction by following them back on Twitter (what up RiRi), others avoid it at all costs. These celebrities, in particular, take it to a new level: they don't follow anyone at all. Whatever the case—simply not knowing how to use Twitter properly or an inflated ego—these are the stars that seem extremely self involved. FYI: It's not a good look.
