The positivity of the Obamas as a family is undeniable.

I don't consider myself to be incredibly confident, or really lacking in confidence. When you're on Jonathan Ross' or Graham Norton's show, inevitably there's something to sell. And there's a live audience; you're sat between Cameron Diaz and Tinie Tempah - I don't really see it as 'me.' It would be odd if it was.

I sometimes have an over-confidence that can be viewed as arrogance.

On stage, you have to have incredible confidence, or you would stop doing it. But I don't think I will ever get to the point where I go, 'I know exactly what I am doing,' and I don't think I want to.

I haven't always voted for the same party, mostly because I find that strange. One thing I've never quite understood is when people say 'I'm a Conservative' or 'I'm Labour,' before even hearing what the person running stands for or wants to change.

BBC3 even started their biggest shows, like Jack Whitehall's 'Bad Education,' they premiered on the iPlayer a week before it went on TV. I think it should always be at the forefront of what is fresh and exciting, and therefore it should be the first channel to exist online.

The truth of why I used to listen to Arrested Development on my Walkman was because if I didn't, it would take me 20 minutes to walk to school. If I did, it took me 15. That's the reason I loved it. I just had more of a kick in my step, more of a bounce, so I'd walk quicker.

Nobody tells you when success comes around; in its transient way, you're just working and exhausted all the time. Sometimes I think I'm just sleeping in the back of cars, d'you know what I mean?

You used to have to come to America for 18 months and drive around in a van, trying to get radio stations to play your song. But I remember One Direction's manager telling me that the first time they came to America, they hadn't released a song - they'd only been on 'The X Factor.' But there were 2,000 fans waiting at LAX airport.

I'm very lucky, in that I've known Adele for quite some time.

I've been lucky enough that in the U.K., I've done shows that have aired once a week. I make a show there that runs seasonally, and we make one episode a week, and that is great - the value of time. You can really think and finesse what you want to do.

Oh my God, I never really tweet, but there's a moment every day I write one and then delete it.
