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

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 never been engaged. I definitely believe in the institution of marriage.

By preventing pneumonia and other diseases, we are giving men, women and children the chance to live healthy productive lives and participate in the global economy. In doing so, we are not only enhancing their futures - we are enhancing our own.

In 2009, I traveled to South Sudan with my organization PSI. While there, I visited a local school and met with a group of children who had formed a water club. The group learned about how to treat their drinking water and use proper hygiene practices, such as washing their hands before eating or after going to the bathroom.

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.
