The Prince and Princess of Wales have celebrated Prince Louis’s eighth birthday by sharing a new photo of the youngster onboard a boat during a family holiday to Cornwall.
A grinning Louis is shown leaning with his arms folded against the vessel’s metal barrier, with the sea in the backdrop.
William and Kate’s youngest child, who is known for his cheeky nature, is wearing a blue textured quarter-zip style jumper.

The post on Kensington Palace’s social media read “Happy birthday, Louis! 8 today!” followed by a red balloon emoji.
The picture was taken earlier this month by photographer Matt Porteous, to whom the Waleses often turn to mark family occasions.
William and Kate and their children spent Easter together, and Louis was last seen at church with the rest of the royal family on Easter Sunday.
Sea-faring runs in the family. Louis’s great-grandfather Prince Philip, the late Duke of Edinburgh, was known for his Naval service, and became Admiral of the Fleet.
Louis’s grandfather the King also served in the Navy as the Prince of Wales, commanding HMS Bronington, and Louis’s namesake – Earl Mountbatten – became the First Sea Lord.
