Today, Queen Elizabeth II’s great-grandson Prince George celebrates his ninth birthday. On this occasion, the Dukes of Cambridge published his new photo.

The picture was taken by Kate Middleton during a family holiday in the UK earlier this month. In the photo, Prince George bears a striking resemblance to his father, Prince William. The heir to the British throne smiles broadly as he poses for the camera in a light blue collared shirt.

Recall, Prince George Alexander Louis, known as His Royal Highness Prince George of Cambridge, was born on July 22, 2013. He is third in line to the British throne after his father, Prince William, and before him, his grandfather, Prince Charles.
