Anyone called George is being given free admission to Newmarket Racecourses on Saturday to celebrate the royal baby.
Georginas will also be admitted free of charge to The July Course at the Headquarters of racing.
Amy Starkey, Regional Director – East, of Jockey Club Racecourses, said: “Newmarket Racecourses, like the rest of the country, was thrilled with the birth of baby George to the Duke and Duchess of Cambridge."
The Duke and Duchess of Cambridge proudly showed the world their baby son, a future king, before taking him home tonight.
The royal baby appeared to wave as he was introduced to the crowds outside the hospital for the first time.
It's been revealed the new Royal parents and their new son will be making a family home at Anmer on the Sandringham Estate in Norfolk.
