Its just a vicious cycle.  You've got the high falutin' snot that thinks she's all that, then you've got the Idol worshippers, that have to follow her every move because they don't have enough interest in real life/self esteem/courage to go out and live their own lives, which in turn boosts the high falutin' snot's pride and ego, which causes her to give more fodder to the mass of human lemmings, which reciprocates with more love and adoration.
