Growing up in the public spotlight and having insecurities like every other girl, I really know what it's like to feel self-conscious.

Music is my first love.

I write a lot on airplanes actually because it's completely isolating; there's no one to talk to, there's nothing to do.

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'm really kind of boring - I'd rather go to bed early and get up early because I really value my time off, my time away from work.

I carry around a little journal with me, a little notebook and a pen and just write all the time. Not necessarily actually sitting down and writing lyrics, just free-form writing, whatever's going on in my mind.

I kind of feel in a way all of us will forever be asking those questions of ourselves. Who am I and how do I fit in in the world and what is all this about? Because those aren't really... there are no answers to those questions in a sense.
