There's part of our brain that we shut off when we're in the studio. There's part of our brain that we turn on when we are out doing an interview or promoting something or waking up at six in the morning for hair and makeup.

I've learned when to get out. I've never wasted too much time with the wrong person, and that's one thing I'm proud of. The longer you're with the wrong person, you could be completely overlooking or not having the chance to meet the right person. And if it doesn't feel right, it isn't right. How do you know if something feels right? I think the great defining factor for me is whether I want more. When they drive away, do I wish they would turn around at the end of the street and come back? Or am I fine that they're going home?

Money can't buy you back the love that you had then

We leave a piece of ourselves and our magic in a person that we fall in love with.

I think everyone should approach relationships from the perspective of playing it straight and giving someone the benefit of the doubt. Until he establishes that this is a game. And if it's a game, you need to win. The best thing to do is just walk away from the table.

You have to be happy with who you are and the choices you make. If you don't like yourself, you'll never be truly happy.

I have never used Auto-Tune in a live television performance, and I have never used Auto-Tune in any of my concerts. That is a promise.
