My first real crush was... Louis Tomlinson.

The first time I had sex, I was scared I got the girl pregnant. And that was despite the fact we were safe. Luckily, we were fine. I would never risk not wearing a condom, it’s too much of a risk. If you’re not ready for a child, then don’t risk it.

I quit shoelaces a long time ago.

I’ve got four nipples. I think I must have been a twin, but the one other went away and left its nipples behind.

I don't want to be one of those people that complains about the rumours. I never like it when a celebrity goes on Twitter and says, "This isn't true!" It is what it is, I tend not to do that. The only time it gets really annoying is that if you get into a relationship and you get into a place where you really like someone and then things are being written in the papers that affect them and how they see you. Then it can get annoying.

I've got a really good family; I've got great friends around me.

You get moments all the time that kind of make you pinch yourself, some of them make you quite emotional. Winning a BRIT was a big moment because we were just so excited to be at the awards in the first place. Selling out Madison Square Garden was pretty amazing too. Then we woke to the news that our UK tour was sold out. It was crazy.
