The Prince and Princess of Wales have marked Louis's birthday with a post to social media.
A picture of a grinning Louis, leaning with his arms folded, in a blue textured quarter-zip style jumper, was posted to Instagram on Thursday.
The caption read: "Happy birthday, Louis! 8 today!" followed by a red balloon emoji.
William and Kate's youngest, Louis is known for his cheeky nature.
The picture was taken earlier this month by photographer Matt Porteous, to whom the Waleses often turn to mark family occasions.
