It depends on the scripts and the character and just everybody involved, the other actors and directors. It's just a gut feeling when you find something, you're like, 'Yes, I want to sink my teeth into that.'

I guess I have sort of an atypical relationship with my mom for someone my age, because I think I started so young with the music thing and I had my parents always on the road with me. So at a time when I think I should have been rebelling like in high school, they were actually my best friends.

I write a lot on airplanes actually because it's completely isolating; there's no one to talk to, there's nothing to do. And then I think a lot of it sort of comes out sitting down with the people I'm co-writing with and talking to them about what I'm going through and what I want to say. It just sort of happens; every song came about in a completely different yet organic way.

I've had the opportunity to play the drug dealer who gets gang-raped, and I'm like, "For what reason? Doing it just to do it? To just show people that I can be sexy or dark?" I don't want to do something just to make that point. It needs to happen organically, and I'm really confident it will. I'm a pretty patient person, and I'll wait until we find the right stuff.

I've always had bad posture, and Pilates makes me feel taller and reminds me to keep my shoulders back. And hiking isn't just about doing cardio, it's also when I can get my 'me time' to be alone with my thoughts. After Pilates I should do some cardio, and after hiking, I need to do some resistance training.

I travel the world visiting global health programs as an ambassador for the global health organization, PSI, and sometimes the disconnect I see is truly striking: people can get cold Coca Cola, but far too infrequently malaria drugs; most own mobile phones, but don't have equal access to pre-natal care.

I love music and I guess I have less expectations or pressure to kind of put on myself because the music hasn't been some huge sensation.
