She's only 20. I'm probably in the minority here, but I feel like, why can't these tennis players find someone their own age to date? It's not as bad as Philippoussis and his (barely legal) girlfriend, or Stepanek and Vaidisova, but it still weirds me out a little. I mean, 20 seems pretty young to be getting married.
Someone that age is easier to manipulate and more willing to conform their personalities, likes, and goals to fit that of their partner for the sake of the 'relationship'. I suppose she has the sort of passive parents that feel if she is old enough to model in SI, she is old enough to make major life decisions like getting married.
She should take a second look at this situation, because she can't be beautiful forever and might actually need some sort of education in case things with Andy do not work out and she is a divorcee. There is nothing worse than having to depend on a man for money.
