I will always be the older sister. That's never going to change.

Some people say I have attitude - maybe I do...but I think you have to.

I just try to stay positive and focused on the tennis, not let anything get to me, like crazy questions. But I'm tough, let me tell you, tough as nails.

There is nothing like playing at Wimbledon; you can feel the footprints of the legends of the game-men and women-that have graced those courts.

The outfit is inspired by Alice in Wonderland. It's kind of about a surprise, because when Alice goes down the rabbit hole, she finds all these things that are so surprising. This outfit is about having a surprise in a tennis dress, and showing some skin and then just having a print. Prints don't happen that often in tennis. So it's called the Wonderland dress.

Grand Slam losses are hard. I treat myself after losses though, I usually go to McDonald's and I have a hamburger and you know, something. Because you know, you just need to be nice to yourself sometimes after the loss.

I always like to win. But I'm the big sister. I want to make sure she has everything, even if I don't have anything. It's hard. I love her too much. That's what counts.
