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.

Throughout the history of Iceland, men have been lost at sea; every family in Iceland is connected to that kind of story.

I am from an F.D.R. liberal-Democratic family. With proximity to government, I have become more libertarian.

My son and daughter lost their father quite young, so we keep him present with us. It's just a daily practice.

I consider myself fortunate that in my home, acting or the creative arts were a good option. This was a respected tour of duty in my family. Acting wasn't something that was left to tragic bohemians. But we weren't a family that obsessed on cinema.
