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 always think about the simplest things in a relationship that have frustrated me. It always sort of comes down to communication. Even something as simple as probably the worst thing that could happen is, 'Where do you want to go to dinner?' 'I dunno. Where do you want to go to dinner?' 'I dunno.' That might be the worst thing in the world.

I carry around a little journal with me, a little notebook and a pen and just write all the time. Not necessarily actually sitting down and writing lyrics, just free-form writing, whatever's going on in my mind.

I've had fun doing romantic comedies, but I just can't anymore. There's nothing fulfilling creatively, there's nowhere to grow, nothing to learn from it or for yourself. I'd rather just be home with my family or write music until that special project comes my way.

Worst thing in the world? John is completely out of it. Good luck, ladies. He's a freak!

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