The link between my brain and my mouth is just not there anymore.

I have been lucky, of course. Like, last year, if I went out, I'd have to fight to chat someone up. This year, I look exactly the same, which is really scruffy, and yet lots of people seem to have just changed their minds and decided I'm really sexy.

The first period of getting famous was incredibly strange to me and really fun at the beginning because you didn't realise the consequences of anything. You could say or do whatever you wanted and it just didn't matter.

If you took away publicists and things and people spoke for themselves, then they'd have to be responsible for their words.

I was really unfit last year, so I worked out for a long time, then spent time by myself in Oregon. For about two months the only person I saw was my trainer. Every day I did a lot of running and I just didn’t want to talk to anyone for two months. So when I started talking again, it was like you would communicate wrongly, like you wouldn’t really remember how to speak. That was one of the key things as well as just reading the book, reading the script a million times, just figuring things out.

People don’t find the personal lives of people with much, much more power than any celebrity would have — don’t find their personal lives interesting. I think if you put the lives of people who controlled billions of dollars on the front news of every single paper, the world would be a better place. It’s the spin culture. If you took away publicists and things and people spoke for themselves, then they’d have to be responsible for their words.

We didn't have packed lunches at my school. I was a lunch monitor as well - I used to take everyone's chips!
