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 think communication is key, too. You're answering all the questions. Thank you. I'll just sit back here.

I was happy to kind of always scoot under the radar.

As an Ambassador for PSI and a supporter of Nothing But Nets, I have met individuals around the world who are lending their ideas, their voices, and their time to improve their communities and the world at large. And there are millions more that I have not met.

I'm minimalistic when it comes to makeup, so I'm a sucker for anything that's multi-tasking. Aquaphor is my go-to product. It's great for adding gloss to eyes and cheekbones, and amazing for soothing dry cuticles, too.

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.

Robin [Williams], he's pretty dynamic. I had a lot of fun but I also felt like there was no onus on me to be funny.
