Kensington Palace has released three new images of the youngest child of the Duke and Duchess of Cambridge, Prince Louis, in celebration of his first birthday.

While the world patiently waits for the newest royal, Baby Sussex, to make their debut into the world, Prince Louis and his family have just finished celebrating the youngest member’s first birthday, which is on April 23.

The adorable photos were taken by none other than his talented photographer mother Duchess Kate at their Norfolk home Anmer Hall earlier this month. Shown is the beaming young prince posing in the Anmer Hall grounds on a moss-covered seat.

The family is enjoying their home away from home while Prince George and Princess Charlotte are on their three-week school break.

The angelic tot sat happily dressed in his older brother’s hand-me-downs – a denim blue Thomas Brown Little Puppy knitted sweater and a plain collared shirt. While his gaze his more serious than in the other two images shared with the world, his two bottom teeth can be seen poking out.

In another outfit where the young royal is pictured smiling excitedly in a cheeky and angelic grin, he is wearing a Rachel Riley Peter Pan collar shirt underneath a burgundy marl knitted jumper.

While 5-year-old Prince George was often dressed in shorts as a baby, Prince Louis’ has been photographed in navy blue cords with matching tights.

“Such a mix of Charlotte and George,” one excited royal fan commented.

“Stunning little prince, resembling so much both his parents!” another comment read.

“My heart is melting,” another added. “I need to give him a hug!”

The first birthday portraits of the one-year-old royal member are reminiscent of the Cambridge family’s Christmas card photo where the happy group of five were pictured within the same grounds of Anmer Hall.

It is not the only time the Duchess of Cambridge has polished off her camera and snapped pictured of her family's milestones over the years. Not only has she been behind the lens for Louis’ first official portraits, she was also taking snaps of her other two children Prince George and Princess Charlotte.

Prince Louis Arthur Charles was born on April 23 at 11:01 at the Lindo Wing at St Mary’s hospital in Paddington.

Prince William and Duchess Kate are travelling to New Zealand on Tuesday to honour those affected by the Christchurch terrorist attack that saw 50 lives lost.

The couple are also set to celebrate eight years of marriage on April 29.
