Amy and I got back from our week in Michigan yesterday (more on that in a future post), and we shared a flight with Amy Smart (Tasty Coma Wife on Scrubs, Just Friends, etc.). I wasn't sure it was her, but I saw her on the plane and picking up her luggage, and it looked a lot like her. She was dressed well and had a dog. I looked up her profile on IMDB and it turns out her parents live in Michigan and she has done some commercial work there. So it was probably her.
I haven't seen many celebrities "in the wild," so it was kinda cool.
