Little Things isn't about anyone in particular, it's about all girls. You're all beautiful and you need to hear it more often

We needed to make a sound that's not gonna fit in with everything else - we wanted to make something that was completely unique and individual to us. We spent a lot of time trying to make a sound that was a One Direction sound. At first it was quite hard to do that, but I'm really happy with the sound.

My trademark saying is probably “VAS HAPPENIN?!”

I was a bit of a handful when I was a kid because I was quite hyperactive. Even in the house my mum used to put me in my pram because I was so full-on.

Without the fans there's no reason to be One Direction.

and remember, nobody's feelings are more important than your own, so take time to love yourself.
