The third-in-line to the British throne has turned three, and Kensington Palace has released a series of photos to celebrate.
Photographer Matt Porteous captured the new photos of Prince George, decked out in impressively clean clothes for a three-year-old, at the Duke and Duchess' family home in Norfolk.
"Can't believe it's been three years already!" the palace tweeted.
The family has thanked everyone for the birthday wishes the young prince has already received.
It's believed the young prince is to mark the milestone with a party hosted by his parents.
