In honor of Prince Louis' fourth birthday on April 23, Kensington Palace released an adorable portrait photo of Prince Louis. In the photos, taken by his mother Kate Middleton, the Duchess of Cambridge, Prince Louis, now 4 years old (since it's already Saturday in the UK!) ), is laughing and playing on the beach near the family's home in Norfolk, holding a ball and wearing a starched gray sweater.

"Four years old tomorrow!" the Cambridges' official Instagram account captioned the photo.

The Cambridges just returned from a ski trip to Courchevel in the French Alps, where Us Weekly reported: "During the pandemic, George begged William to take him skiing when everything resumed, and his father obliged." The kids loved playing in the snow, having snowball fights with Kate and William and building snowmen," the source added.

Before their ski trip and Kate and William's contentious royal tour, Prince Louis was spotted by an eagle-eyed royal fan walking his dog with his father, Prince William, in Kensington Gardens in London.
