I have been styling my own hair since I was four years old. . . and I still don't let anyone else touch it to this day. I cut, color, style, and spray my own hair, on all sets and shoots, that's just the way it goes. I get way too nervous when someone else starts to mess with it.
That's what so great about making movies. It's that you get to do stuff you never would be able to do in real life. You get to go to a recording studio, you get to go to Navy ships and fly all over the world for press. And it's just a great job.
