It felt when I was growing up that sport was, like, the only thing you should do... if you do music, you're really different and a bit weird.

I'm involved in music and fashion a lot more than I used to be, so my style has definitely changed - for the better, of course. It's given me greater insight into what colours work, what looks good on camera, and what I feel comfortable in.

I've only really had one period when I lost myself and felt like I was going to lose my career, and that was when I first began presenting 'X-Factor' spin-off 'The Xtra Factor' two years ago. I was worried if I did a rubbish job live on Saturday night TV that my music career was going to get affected and I would lose everything.

I'm a huge fan of 'Heart On My Sleeve' - I think it has a 'Take That' feel to it! John Shanks and James Morrison wrote the track, and we spoke to Sony and asked if we could reference a 'Greatest Day'/'Rule The World' sound to make that epic ballad. I think it does the job.

The efficiency, credibility, and liquidity of the financial markets have been foundational to the largest economy in the world.
