I'd like to work with Justin Bieber. He's talented and he's so young. I know what he's going through. I've lived what he's living through right now. Working with him would complete a circle of sorts for me. And he might find it a worthwhile experience himself.

By learning about my body and making small subtle changes I find out what I enjoy and what is effective. I'm always finessing: adjusting my diet and my workouts. You have to figure out which exercises are fun and interesting and stimulate your brain - or else you'll never keep at them.

Justin Timberlake is everything and what more could you want in a person? He's funny. He's cute. He's great. He just understands. I get him and he gets me and that's cool.

I'm not a movie star. People know me but they don't necessarily know what they know me for. I get recognised but it's not like Justin Bieber. It's a nice thing people are cool.

It could be fun to sing with Prince or Michael Jackson. Justin Timberlake has an amazing new sound now.
