Gallery: Pictures of Famous Athletes When They Were Kids

What did famous athletes look like when they were kids? Well, cute and adorable certainly came to mind when the photo editors of Sports Illustrated put together the gallery below of LeBron James, Tom Brady, Serena Williams and others when they were kids. Silly fits in some cases too, as you'll see when you click through the picture show.

We're certain their parents had no idea their sons and daughters would grow up to be some of the greatest athletes in the world. We're also sure that the athletes pictured here giggle at their own photos when they look at them. We think you will too. Enjoy.
