I didn't realise how important stupid people are in your life, because you ask yourself, what made stupid people so stupid? What made them the way they are?

I was slightly cynical of the American mentality before I came over here, but now I preach it. Here, no one's going to tear you down if you buy yourself a $300,000 car. They're likely to say: "Well, you probably worked hard for it. Good luck to you."

My proudest achievement has been the success of the shows and artists I have been involved with, because they were made in Britain.

In TV, film, and music there's a lot of snobbery, and I don't like it. I've never been a cultural snob.

Have I got a black book? Yes, it's called a mobile phone. I do get offers. There is no shortage of people if you want to go on dates - working in TV, living in L.A., it is there if you want it.

I like to know why a video has suddenly gone viral, why a song has broken, why a TV show is suddenly rating out of pattern... I'm pretty good at understanding why things are becoming popular.

I actually don't understand a word Paula's saying anymore. It's like a new language.
