You always hear all these stories about what a  diva Jennifer Lopez is. For some reason I hope  they are not true, she seems like a genuinely nice down to earth person. Well the latest off the set of American Idol  is that she is very personable and sweet to guys on the set. But, as soon as the guys leave if any females are near her, she becomes very short tempered and rude.  Whew, good thing she is the only female judge on the  set. So much for leave your ego at the door.
