I think people I'm close to find it absolutely crazy that I'm famous.
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.
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.
You can say whatever you want about me, I'm not really bothered. But when it starts to upset people I care about or I hear about it from my mum, then that's a problem.
When people are putting pressure on me I just completely ignore it.
If people talk behind your back, it's because you're ahead of them.
No matter how many times people try to criticize you, the best revenge is to prove them wrong.
It's pretty strange because you have images of people in your head when you left, then you just think they're going to be the same when you come back, like time freezes. I have sisters and from the ages of 11 to 13 - it's a big change for girls.
Before you judge people, judge yourself.
