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.

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

Rap and dance is pretty much what I want to be known for.

It doesn't help anyone to judge their happiness or career by looking at where others may or may not be. Dad said it best: 'All the time you're looking left and right at other people, you're neglecting what's in front of you.If you focus on looking straight ahead, you can take the odd glance at the future.' He's got a way of saying things sometimes that just puts everything into perspective.

To be honest, all I wanted to do, all I ever, ever wanted to do - I just wanted to perform.

It was a chance meeting with a lady at Mariah Carey's record company who was here in our office, actually. And I pulled her in here to this very office that we're sitting in now, and I played her the clip of me and George Michael singing. And I was like, it's joyful. And that's what people want.

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 .
