Everybody goes through their life in different ways. I definitely am having my journey. It evolves and changes. At some moments, I feel totally off center and trying to find my way back.

I'm the cofounder of Keep a Child Alive. We provide medicine for families affected by HIV and AIDS in places like Africa and India.

So we come together before you on this day, March 30th, 2015, with one voice in unity in the hopes that today will be another one of those moments in time, a moment that will forever change the course of music history.

When I'm on stage, my interaction with the audience is something that really makes me come alive. It's a feeling like no other. The energy of the crowd fuels something new inside.

You're at your most purest, most innocent, pure state when you're doing something you've never done before. You're scared a little, you're a little vulnerable, you're kind of trying, and then you're also better, because you're trying harder than you maybe would try.

A lot of people, they've been saying to me, oh don't get married. It ruins everything. And I'm like, damn.

I find that the love we share fills me up and makes me see and appreciate life in a different way.
