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

Because I'm in an adult world and I'm really working, my age is just a number. It's not really who I am.

I take advantage of the opportunities that have come my way. I think I've lucked out that I've never been thrust in the spotlight where people wanted to dissect every aspect of my life. I've been given a lot of distance and respect. It's allowed me the best of both worlds. I have the job of my dreams, but I also have the freedom that doesn't always come with it. I feel very lucky in that sense.

Tackling malaria in a country like the Central African Republic is a huge uphill battle, and my experiences there have been a healthy dose of reality, fueling my own sense of urgency to do my part in reducing the preventable suffering of the incredible women I met.

There's so much to explore! And personally, I don't know. It's such a crapshoot.

Those situations are weird. You're in a room, and I knew they already loved this guy [for the role], so you're like, "OK, this is a different dynamic."

I love film, but it's bringing me away from music. Singing is what I'm probably most passionate about.
