There are people in America who are absolutely desperate right now, who have no means to support their families, who have no opportunities to better themselves or their education - and they're not that different from the farmers and working-class people that I visited when I went to Kenya with Oxfam.

Having visited Oxfam-funded school programs in rural communities has made me realise how vital education is to developing countries in bringing people out of poverty and giving them a sense of dignity, self-worth and confidence.

I don't feel the need to brand myself in that way [social media]. But as a means to share information and raise awareness of things, I think these social-networking platforms are unprecedented.

I've always been very focused on my career. But, it's good to have people [say], "Okay, you need a vacation." "I do? Oh yeah, you're right. I think I do."

I'm not anxious to starve myself. For me, it's not at all sexy to be ultra-thin.

I love musicals, I started acting because I wanted to be in a musical.

I don't go to McDonald's anymore. After I saw Super Size Me... no way!
