She just always seems so upbeat and carefree all the time, not at all full of complaints about how badly she was worked on Grey's Anatomy (even though she was in a coma for approximately forever), or how Knocked Up was an embarrassment. And I bet she had Demi Moore quaking in her proverbials when she heard Katherine was working with Ashton, 'cause the Heigl is such a barrel of hoots!

For example, of their time filming Killers together, Heigl said: "He was really mad at me because I wouldn't do my own stunts. He was only partly joking when he said that I probably even think running is a stunt. Actually, I do, because it's dangerous. I have bad feet and I have weak ankles. If you have to do it over and over again, you can hurt yourself. Anyway, Ashton was always just rolling his eyes at me."

Just his eyes? Not his whole head? Aaaah, you probably informed him the crippling dangers of rotating his neck over and over again.

Katherine, during promotional interviews for the aformentioned film, is remaining typically upbeat regarding an array of topics. Of her newly adopted daughter, she said: "It could all turn to crap when my daughter turns 13 or something. But, I think as of right now, we (that being herself and husband Josh Kelley) are so into it and confident as parents like, 'We're in charge.' We're the cliche, typical couple who's talking about poopie diapers and stuff. We're always communicating about those more than we probably talk about anything else."
