I brought a lot of my own pieces of clothes to the design room when I first met with the design team just so they could see what my style was like.

The first time I walked into the Olympic athlete village seeing the Visa ATM machine with my picture on it and the Chinese characters saying 'Destiny.' For some reason, it just boosted my confidence and it was before I had even worked out or had my first training or competed.

I have always loved clothes, and the opportunity to design my own line could not be missed. It's a dream job.

I do a lot of co-writing with my producer RedOne, and then a lot on my own. I just like to be creative.

I was brought up Irish, where there was room for my own private world.

Like at home, I don't wear heels. But everywhere else I go, I wear heels.
