Mitchell Souter wrote to the remake of cult TV show Jim'll Fix It, which aired on BBC1 on Boxing Day, asking to join the Formula One star's team.
He was thrilled when his wish was granted.
The 12-year-old was taken to Goodwood for filming on December 9 but had no idea Lewis Hamilton would actually be there until he arrived.
Mitchell, who goes to Altwood CE School in Maidenhead, has been racing cars himself since he was 10.

The youngster was given a Jim'll Fix It medal, a signed replica Lewis Hamilton helmet and a framed photo from the day.
