I've developed a karaoke habit. I've become a crooner.

I decided I can't pay a person to rewind time, so I may as well get over it.

Someone like Billie Jean King is completely my idol.

If I have a daughter and she plays tennis, and I have a son who plays tennis, I wouldn't say that my son deserves more money because he's a man. I would say they deserve the same amount of money.

When I first started really playing, in '98, I was super excited to see all the people I grew up watching. ... I loved Monica Seles, Steffi Graf, and Pete Sampras.

Since I don't look like every other girl, it takes a while to be okay with that. To be different. But different is good.

I've never felt invincible. I've never used that word to describe me ever.
