Someone famous?

I was on the plane and in the next row were two very cute kids and their mom. The little girl was 5 and three quarters (as she told me) and very cute. She and I chatted periodically through the flight. We talked about pelicans and the movie Finding Nemo and her brother and where she was on vacation and where she is going in December. She was very chatty. When we were getting off the plane I helped her mom carry down a big bag since the boy had fallen asleep and the mom needed to carry him. At the baggage claim they were met by a guy from a car service. Now I'm totally curious as to whether or not they were someone famous. :)
