I do find it bizarre that people find it bizarre that I've grown up.

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.

I guess at a certain point you think, well, singing is singing and acting is acting.

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.

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 think I found it difficult though to keep a straight face when we were actually working and I wasn't supposed to be laughing.

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."
