Sometimes you work all the way through to 5am, then get a few hours and you're back on set again.

Whenever I wasn't in school with a tutor three hours a day, I'd get a knock and be rushed to set and they'd be waiting and I'd film my thing and then I'd go back to school again.

I love England though; I've been back a few times and just love it. My favorite thing to do there is going to museums and all the castles. Oh, and my husband and I went mountain biking across England on our honeymoon!

I get letters from kids, teenagers and young girls who just want to be Mac. I've had quite a few people actually say that they're going to become a Marine or a JAG lawyer because of me... the character. I think that's pretty cool!

But, people are recognizing me more. Sometimes fans just approach me on the street and say how much they love the show. It's great to get that kind of feedback.

I started when I was in college because I was shy and thought it would be a good way to break out of that.
