There were a couple of years where I got a bit lost - I went out too much, I was a bit heartbroken, thought I was a bit more of a dude than I really was. I would love to go back and have a strong word with myself.

I guess I have a faith. I have an overriding feeling that all of this can't be for nothing. But then I also fully understand that it might be.

I just wanted to perform. I just wanted to perform in whatever capacity, whether it was acting, singing, dancing, comedy - whatever it was, I just loved it and felt at my absolute happiest when I was performing for people.

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.

I love hard work. One Man, Two Guvnors was so physically tiring I ached all the time, but I took a massive amount of pride in the fact that I only ever missed two shows.

There's nothing more creative I'll ever do in my career than trying to make an hour of TV everyday.

If our show [Carpool Karaoke] shines, then I shine. I don't ever want to come out and make anything about me. I want to make it about them, make them the best that they can be. And the whole thing is a collaboration, those carpools.
