It´s because the fans likes to make either a bad girl or a good girl out of the player.
Bad Girls like Justine, Maria, Nicole, Nastya, Patty (and some other) are mean, hate everybody, cheat, lie and everything they do, think or dream is really, really baaaaad.
Good girls like our Kim and maybe Elena D., Ana, Daniela (and some other) are always cute, honest and everything the do, think or dream is unbelievable sweeet.
Ok, serious...every human has good and bad sides. Even a Kim Clijsters.
It´s hard to believe, but it´s true.
