I prefer to date younger girls to be more protective.

When we were on 'The X Factor,' we didn't realize how overnight the fame thing was. We didn't really understand it until we went on a shopping trip. It was like Week 7 or 8 of the show. We went with a few other contestants and there were loads of people, packed.

We didn't really expect to achieve anything outside of the UK, and it just went crazy. It's just crazy that people know our music. We're just humbled by it.

I love the fact I grew up wanting a brother and now I have four.

Live for who and what you love.

I do believe in love at first sight. I'm experiencing it everyday.

I'm a massive fan of Drake, and we walked right past him. He's too cool to be clapping One Direction though.
