The four-year-old royal's father Prince William was beaming with pride when he went to watch his son in the traditional Christmas play and couldn't wait to tell people all about it.

Speaking to school children at BBC's Bridge House in Media City, Salford, north England about their Christmas plans, he said: "I went to my boy's nativity play. It was funny. He was a sheep."

It comes after the Duke of Cambridge hand delivered his son's Christmas list to Father Christmas during a recent trip to Helsinki, Finland, after George promised he had been a good boy this year.

Prince William - who also has two-year-old daughter Princess Charlotte with his wife Duchess Catherine, who is also pregnant with the couple's third child - said: "He hasn't written down many requests, so I think one request is probably OK."

The pre-formed list offered the option of writing down five gifts they would like, however George only wrote down one - a police car - before signing it off with his name.

The Kensington Palace Official Instagram account shared a picture of William meeting Santa.

The caption reads: "Prince George's Christmas Letter! The Duke of Cambridge hand delivered a letter written by Prince George to Father Christmas at Esplanade Park in Helsinki. HRH is currently on Day 2 of #RoyalVisitFinland, which coincides in the year of the country's 100 year anniversary of independence. (sic)."
