If you've stacked on the weight over time, and if you don't have any health issues, you don't realise. So you'll see yourself in the mirror and, yes, you know what the scales say, but you don't actually see what other people see.

I don't feel I was ever a 'famous' child actor. I was just a working actor who happened to be a kid. I was never really in a hit show until I was a teenager with West Wing playing First Daughter Zoey Bartlet. In a way, that was my saving grace - not being a star on a hit show. It kept me working and kept me grounded.
