I'm able to be a normal mom for the most part. I'm in [clothing store] Brandy Melville like all the other moms.

[When] you're dying laughing because your three-year-old made a fart joke, it doesn't matter what else is going on. That's real happiness.

I used to say to my dad, 'How did you and Mom stay married for all this time?' and he'd say, 'Two things. Number one: You gotta have the same dreams. One person can't be daydreaming about walking down the street in Paris, the other person want to work in a coal mine. Number two: We never wanted to get divorced at the same time.'

It's really hard to find things that are worth leaving them for. [Balancing work and motherhood is] really hard. One night in Nashville, my son was screaming with a terrible stomachache. I was like, 'I have to get out of here!' but we had to finish. My friend Jenno, a mother of three who was producing, was great, reminding me that nine times out of 10, they just have gas.

Some days I feel like everyone in my world has plugged themselves into my kidney. I'm so tired. But when you're having dinner with your kids and your husband and someone says something funny or you're dying laughing because your three-year-old made a fart joke, it doesn't matter what else is going on. That's real happiess.
