"The Duke and Duchess hope that people will enjoy seeing these new photographs. They would like to thank everyone for all the lovely messages they have received as Prince George celebrates his third birthday," Kensington Palace said in a statement.
The photos were taken at Anmer Hall, the royals' home in Norfolk. They show an adorable Prince George with the family dog, Lupo, and on top a swing engraved with his parents' names in the family's garden.
The photographer Matt Porteous said in a statement, "I really enjoyed the opportunity to take these photographs of Prince George. It was a very relaxed and enjoyable atmosphere. I'm honoured they have decided to share these images with the public to mark his third birthday."
It is anybody's guess what the little prince might unwrap this year. He is a fan of the British animated kids' shows "Fireman Sam" and "Peppa Pig" and the childrens' book "The Gruffalo." He is also, according to his parents, obsessed with tractors, planes trains and anything that flies.
The Duke and Duchess of Cambridge are trying to raise their son away from the prying eyes of the paparazzi and, to the extent possible, provide him with as normal an upbringing as possible.
Instead of a fancy private school, George attends the local Montessori school near his Norfolk home three days per week.
When George is ready for his next school, the royal couple is considering schools for him both in London and Norfolk.
Both William and Harry attended the Weatherby School in Notting Hill, which is a stone's throw from Kensington Palace, the family's London home. Kate and William insist they are also exploring schools in the country near their Anmer Hall home for George.
