The youngster, aged five, has a number of hobbies, such as making pizza with his mum, the Duchess of Cambridge, and playing outside with sister, Princess Charlotte.

But he has become particularly fascinated with one particular subject and takes any opportunity to chat to his doting mum and dad about it – dinosaurs.

Prince William revealed little George can’t get enough of learning about the prehistoric beasts.

While visiting Acorn Children's Hospice yesterday, the Duke of Cambridge told a young girl there: ”George is obsessed with dinosaurs. We've been learning all about them."
