The "Frozen" star, who has Lincoln, four, and Delta, two, with her husband Dax Shepard, quipped she needs her morning coffee before she's "nice to anyone," reported Us magazine.
"My current alarm clock is the blood-curdling screams that I wake up to. I bolt down the hallway thinking that someone's fallen out of their crib or broken their arm or, I don't know, drowning in the sink, and then they're just like, 'Good morning, Mommy!'
The 36-year-old actress, however, said her kids make her life better.
"What I love the most is how much kids right size your problems. You don't really care as much. They just make everything better. So all the things you used to worry about just sort of disintegrate.
