It doesn't matter what she looks like as much as that the rumors are not being well refuted yet. She might have thyroid disorder!
I doubt it though.
However, I do not understand how a top-ten player can compete and not be eating. She would have no energy.
This must be a recent thing for her, so it will take time for her to believe that she has a problem. If she is having odd behaviors, I would like to know about them. She sure seems to be under a lot of pressure since she hit number 5 in the world.
Her look is more of a model's look than a curvy adolescent Kournikova.
In certain ways, her look has a higher status, and I think she knows that she is capable of big things as a player and for endorsements.
