'I Know You Care' is about my dad. And I haven't seen him for a long, long time. And my parents divorced when I was really young. And I guess I just wanted a - it was my way of saying that I wasn't bitter or angry anymore. I was just sad and just felt like something was missing.

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 feel like my songs are very relevant and very meaningful, but I literally have to get rid of the nostalgia for shows because I would just be mess on-stage otherwise.

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

The only day I remember of my parents' marriage was the day my dad walked out. As I stood there at five years old, with my older sister and younger brother, I knew that he was gone.

I'd like to look like Madonna when I'm her age. I also look at athletes and love their bodies. I've always wanted to be muscly, not skinny. A lot of women yo-yo around, but I'm always aware if I'm getting a bit out of shape. I never look at the scales but I can just tell. It goes on my tum and bum.

I would like to be mates with Richard Branson because I've hung out with him and he is just the loveliest person and obviously a very rich guy and has a lot of stuff going on, but he's actually a really, really sound person, and he's really positive and he's got a really good energy, so I'd like to hang out with him a bit more.
