I've just done a commercial in the U.S. in which I talk about stocks, shares and bonds. Everyone is amazed. They ask me: 'You really know about that stuff or did you just learn it for the commercial?' I tell them I wouldn't do it unless I understood and had an interest.

I enjoyed my time on the Biggest Loser ranch. Although I will not be returning as a full-time trainer on season 13, I will always be a part of 'The Biggest Loser' family and my commitment to bettering lives through health and fitness will continue.

People don't get to see the unglamourous side.

Boyfriends have to understand me and my needs. They have to know what I want out of my life and about my strict regime. I go to bed at 10pm and not later. I separate my professional and private lives.

I worked very hard and I earned all the attention I'm getting.

I have a lot of boyfriends, I want you to write that. Every country I visit, I have a different boyfriend. And I kiss them all.

When I play, I feel like in a theatre, why should I look ugly then, because I'm a tennis player?
