I never would have thought I would be able to learn as much as I did from Blake Shelton, so I want to open up the doors to working with people that might not make sense on paper, collaborating with different artists like that, because you can never stop learning. That's the most important thing.

There are so many ways to get involved with 'The Voice.' There is the open call, which tons of people are from. Of the people that you saw that made it past the Blinds, the majority are from open call auditions. They went through every round before you see the Blinds. But weirdly enough, I received a phone call.

I don't have the biggest range on Earth, obviously, and I feel like people give me a lot of flak for that, but I don't really claim to have a big range.

I think Dido's really cool. I feel like she kinda tapped in - back in the late '90s and early 2000s - she tapped into the ''90s-does-'70s' vibe.

When you are 28, 29 years old... you are aware that this is going to be your last big contract of your career. You have to make up your mind: What is it that I want? Do I want to find something new, a new culture, a new league, a new language, new teammates, a new city? And what is it that I need to be happy? What is it that I need to perform?

I've only really had one period when I lost myself and felt like I was going to lose my career, and that was when I first began presenting 'X-Factor' spin-off 'The Xtra Factor' two years ago. I was worried if I did a rubbish job live on Saturday night TV that my music career was going to get affected and I would lose everything.

Maybe my job made 0.1% of difference, but Donald Trump did 99.9% of the work, and anyone who tells you different doesn't know Donald Trump.

That was it - I lost my job... I was very discouraged. I wanted to be in defense work... I'm an American, and I have nothin' to do with Japan, and so it's sort of an insult to me.
