It's a corset design making me look very, very slim and trim. I call it a corset dress. Very Hollywood glamour with the silk.

I'm really super feminine, and I'm really soft. I'm very sensitive, I realized.

I'm a big supporter of this product for women. And [my relationship with the brand Berlei] was so organic. I would go to the store and buy 40 or 50 bras every year because I could only get them in Australia at the time. And then eventually they heard that I would come and take all the stock.

I always say if I play my best it's difficult to beat me

Will I have to explain to my daughter that her brother is gonna make more money doing the exact same job because he's a man? If they both played sports since they were three years old, they both worked just as hard, but because he's a boy, they're gonna give him more money? Like, how am I gonna explain that to her? In tennis we've had great pioneers that paved the way - including Venus [Williams], who fought so hard for Wimbledon to pay women the same prize money they pay men, and Billie Jean King, who is one of the main reasons Title IX exists.

Hopefully I'll be able to mature one of these days, get serious, and at least have them [kids] pretty fast.

It's remarkable she [Venus Williams] plays at all, given her Sjögren's syndrome [an autoimmune disorder that can cause joint pain]. She's back, winning tournaments. She didn't allow society to tell her, "You have this disease; you can't do that anymore." I look at her, like, "She's not playing at 100 percent. You are. You don't have excuses." Knowing what she went through helped me try to be a more positive person.
