WATCH: When big Lewis met little Lewis

Lewis Hamilton has fans all over the world after more than a decade at the top of Formula 1. Mercedes shares a heart-warming clip of the four-time world champion meeting one of his biggest fans. Little Lewis, where can we find a hat like yours?!

Last year, one of @LewisHamilton's biggest fans wrote him a letter

Unfortunately, it got lost... But over the winter, we found it, and invited Little Lewis to come and see us

We just forgot to mention that a special member of the Team was there that day too… #DrivenByEachOther pic.twitter.com/jkJs4uR7OS — Mercedes-AMG F1 (@MercedesAMGF1) March 17, 2018
