Prince Louis' Cutest Royal Pics

Birthday boy Prince Louis playing on the beach in a series of new photos taken by his mom in celebration of his 4th birthday in 2022.

Prince Louis holds his mom's hand as they attend a special performance of The National Lottery's Pantoland at London's Palladium Theatre in 2020.

The 2-year-old royal joined his parents and siblings in clapping for carers during the United Kingdom's Big Night In.

Little Louis was one colorful cutie in these sweet portraits taken by his mom, which Kensington Palace released one day before the prince turned two. "Sharing a sneak peek of Prince Louis’s handiwork ahead of his second birthday! ?," read the Instagram post.

Cousin Love! Prince Louis had his tongue sticking out as he reached up toward his baby cousin, Archie, and aunt, Meghan Markle, as both the Cambridge and Sussex families bonded at the King Power Royal Charity Polo Day in Wokingham, England. Princes William and Harry were participating in the July 10 polo match.

Just like his siblings before him, Prince Louis stole the show in his Kensington Palace balcony debut, which took place during the queen's annual birthday parade, Trooping the Colour, in London on June 8. The tot clapped and waved his heart out to the delight of both his proud parents and royal fans. 

Along with his big siblings, Prince George and Princess Charlotte, little Louis helped support his mom with a visit to the RHS Back to Nature Garden, which Kate helped design. In one of the sweetest pics from the fun day, the Duke and Duchess of Cambridge's youngest son can be seen running along a manicured boardwalk with a stick in his hand as his dad carefully watches on.

Happy first birthday, Prince Louis! To celebrate the little royal's big day, Kensington Palace released a trio of sweet new photos taken by his mom in early April at their home in Norfolk. In one of the images, Prince William and Kate Middleton's youngest son offers the camera a wide smile while clad in a maroon sweater. The pink-cheeked youngster's blond hair is carefully combed to the side as he crawls about a lush green space. 

All five of the royal family members were smiling in their 2018 Christmas card, including Prince Louis, who flashed a sly grin. 

We're not sure if any baby looked as excited about his christening as Louis! "The Duke and Duchess of Cambridge have released an additional photograph taken following the christening of Prince Louis. The Duke and Duchess hope that everyone enjoys this lovely photograph of Prince Louis as much as they do. ? @mattporteous," read Kenginston Royal's official Instagram caption.

The Duke and Duchess of Cambridge shared two photos taken on daughter Charlotte's third birthday, including this sweet snap of the little royal giving her baby brother a kiss on the forehead. The Kensington Royal caption read, "The Duke and Duchess of Cambridge are very pleased to share two photographs of Princess Charlotte and Prince Louis, taken by The Duchess at Kensington Palace.‬ This image was taken on 2nd May, on Princess Charlotte’s third Birthday.‬ ‪The Duke and Duchess would like to thank members of the public for their kind messages following the birth of Prince Louis, and for Princess Charlotte’s third birthday.‬"
