Every time I do an interview, it's like serious therapy. But real therapy isn't something that I'd ever have. I feel fortunate that mentally everything is functioning well.

I know I'm a pop star. But sometime I'd like to be a rock star.

My parents are still together. I have two sisters. I travel the world and they are the people I speak to.

We see differences in people and seem to be afraid of people. The black or white or gay or straight - I don't necessarily look for differences but for similarities. We need to be looking out for each other.

I'm pretty sure Adele and James Blunt were dumped by the same man.

I think sensitive is the wrong description of me. I'm British, actually, so quite bad at expressing myself in conversation, as any ex-girlfriend will tell you. I'm probably emotionally stunted.

I always wanted to be a Muppet. So when 'Sesame Street' approached me to guest star, I thought: 'I'm going to be on this!' It's pretty incredible stuff.
