Taken earlier this month during the family's Easter break, the sweet clip was posted on Kensington Palace's social media accounts with the message: 'Thank you for all the birthday wishes.'
The previously unseen portrait of Louis was captured by Prince William and Kate's royal photographer Matt Porteous during a sitting in Cornwall earlier this month.
Prince George, 12, Princess Charlotte , ten, and seven-year-old Prince Louis joined the King and Queen at the traditional Sunday service at St George's Chapel in Windsor.
