I suffer panic attacks which has made me really conscious about my fitness and I have become addicted to jogging. It might sound odd but a lot of good has come out of it. My fans send letters saying they have taken up jogging because I do it.

'I Know You Care' is really personal and fragile for me. For me, it's about losing a family member and also about a breakup. It's about this idea of losing someone for good.

My favourite people to follow on Twitter are... my fans. They make me laugh so much and keep me smiling.

I started getting these attacks in 2009, just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist, who told me I needed to make peace with my panic attacks.

I guess I'm just quite observant and I pay attention to a lot of things. Human behavior really fascinates me.

My hairdresser in the U.K., Adam Reed, has his own line, Percy and Reed, and it's really good. And I use Moroccan Oil and Kerastase as well.
