Good genetics are a start, but I have to go to the gym, look after my skin, and drink lots of water. It's my job to take care of myself and my body. Happiness plays a big part in your appearance too.

I grew up on a dairy and beef farm.

It's been amazing how this crazy career has been created. I feel that it's been given to me. I wouldn't be anywhere without Victoria's Secret.

I get skinnier if I'm very busy.

My ideal Valentine's Day is spending it with someone you are in love with and for that someone to make you feel loved and appreciated.

If I'm on holiday, I'm active on the beach, I play tennis, I run, I swim a lot. It's just about making the workouts fun, I think, and then it doesn't really feel that bad.

I'd love to be a pop star - at heart.
