You have to live hardcore to be hardcore.

Live your dream and never wake up

Harry [Styles] is like a younger brother. We do exercises together then he asks me to prepare a sandwich for the effort.

People sometimes ask if I want to be a solo artist, but it just wouldn't be any fun being on your own.

When you first open Niall [Horan]'s wallet, the first thing you see is a picture of Justin Bieber and a picture of us.

Personally, the worst thing a boy can do to a girl is to ignore her while she's loving him with all her heart.

I think in the industry we're in and the type of audience we have, we're never going to escape the idea of being young. Which I don't mind myself. I mean, who wants to grow up anyway? I don't want to grow up.
