I think people look at me and realize that I am definitely not in line to the throne. It feels very easy living in Great Britain. The world is a much smaller place than it used to be, it doesn't feel like a huge cultural difference living here.

Whatever it is, I just loved it and felt at my absolute happiest when I was performing for people. And if that's what you want from a job, then this is the best job you could ever do.

There's just been a couple of moments where - we did the one [ Carpool Karaoke] with Justin Bieber, which kind of went crazy and I think is at, like 65 million views on YouTube .

It would be really arrogant of us to not have any of the fears.

I'm a professional singer. I have a theory that all actors want to be rock stars, and all rock stars want to be actors. I spent my whole school life forming boy bands.

Stevie Wonder doing [carpool karaoke] it was a massive turning point because he's Stevie Wonder. Like, there's no one else in the world who can go, I don't really want to do it. And you go oh, so it's good enough for Stevie Wonder but it's not good enough for you?

Sometimes you can have a reputation for not being relatable and nice because you had a bad day once. That's the thing. You know, I think that's particularly pertinent with Justin [Bieber] because, like, you just forget how young he is.
