My smile is my favorite part of my body. I think a smile can make your whole body. I want women to know that it's ok. That you can be whatever size you are and be beautiful inside and out.

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 just never give up. I fight to the end. You can't go out and say, 'I want a bag of never-say-die spirit.' It's not for sale. It has to be innate.

I love who I am, and I encourage other people to love and embrace who they are. But it definitely wasn't easy - it took me a while.

I don't want to age myself.

My dad is a marketing mastermind.

I can't become satisfied, because if I get satisfied, I'll be like, "Oh, I've won Wimbledon, I've won the U.S. Open. Now can I relax." But now people are really going to be fighting to beat me.
