Friends of the three-year-old royal's parents, Prince William and Duchess Catherine, have shared how the adorable little royal is already growing into a polite young boy.

A close pal of the couple told PEOPLE magazine: "He's a little boy now. "A proper little chap!"

Prince George - who shares his mum and dad with his 14-month-old sister Princess Charlotte - has already shown he's getting into planes, dinosaurs and is a huge fan of playing ball games.

A family friend told the Mail Online: "He has good hand-to-eye co-ordination and has developed a passion for anything ball-related. These are his outdoor weapons of destruction."

And he makes regular trips to the National History Museum in London.

Duchess Catherine, 34, met with representatives of various museums who have been entered to win £100,000 from the Art Fund and she told Nicky Wilson from Jupiter Artland in West Lothian about their regular trips to the landmark.

Nicky said: "The Duchess said Geroge comes here a lot. We were talking about children interacting with sculpture and contemporary art and he loves doing that.

"He loves 3D three-dimensional sculptures. He does come here [Natural History Museum] quite often."

And earlier this month, he even asked his dad if he could fly a red arrow when he attended his first royal engagement at RAF Fairford in Gloucestershire.

George had asked his mother Catherine, 34: "Mummy, can I fly the Red Arrow now?"

However, Prince William dashed his dreams, and said: "Not right now."
