A rock star is expected to act like a mess, sound like a mess and look like a mess. People don't expect you to show up on time and be a professional. But when you're a pop star, you have to do all that, look perfect and be a role model.
I've always liked music that has a darker vein to it. I come from such a safe upbringing - very stable, classic family, everything's nice and good - I was always looking for something different.
My dream was never to become this unattainable star.
The thing that I love about pop music is the simplicity and the directness of it.
I fight the same way as my dad! I've picked that up from him. We both get angry really fast and very intensely, and then get over it very quickly. You need to be good at apologising if you fight like that.
The very first song I ever wrote was a song called 'Crazy' when I was 11 or 12 with my best girlfriends - we had a girl band. It was about loving a guy who everyone else thought you were crazy for being into.
I was always drawn to the self-destructive kind of way. I thought there was something beautiful about it; I don't know why.
