Tennis is interesting because the women are almost more popular than the men. In the U.S. Open, women even get exactly the same money as the men.

I'm really conscious of the amount of food I eat, but I don't deny myself anything. For example, I have a really big sweet tooth. At the end of the night, if I'm craving ice cream, I might not have the bowl that I would have when I was a kid, but I'll put a couple of scoops in a coffee mug, and I'll eat it slowly, and I enjoy every moment of it.

Here's what I've learned about eating healthy when you're busy: It's all about preparation. Make your snacks on Sunday, and you will be good to go until Thursday or so.

I don't care how much you're working out; when you go to put on that bikini, you're like, 'Oh no!'
