Prince Louis is 5!
Louis, the youngest child of Prince William and Kate, the Princess of Wales, celebrates his fifth birthday on Sunday, April 23.
On Saturday, two new photos of the young prince were released to mark the occasion.
The photos show Louis in Windsor, where the Wales family lives.
The photos were taken earlier in April by Millie Pilkington, a U.K.-based photographer, according to Kensington Palace.
Images released for Louis' birthday last year showed him playing in the sand while wearing a gray sweater with different-colored stars emblazoned across it.
Photos from prior years showed him riding on his bike before his first day of nursery school for his third birthday, making colorful handprint art for his second birthday and, for his first birthday, flashing a smile for the camera.
Louis' birthday comes just two days after what would have been his great-grandmother Queen Elizabeth II's 97th birthday. The late monarch died last September at Balmoral Castle in Scotland.
The young prince's birthday also comes nearly two weeks prior to the coronation of his grandfather King Charles III and Queen Camilla.
The palace has not yet confirmed whether Louis or his older sister Princess Charlotte, 7, will attend the coronation, but their older brother Prince George, 9, will have a special role in the high-profile event.
George will serve as one of four Pages of Honor for Charles at the May 6 coronation at Westminster Abbey. George and his fellow pages are expected to process behind Charles in the ceremony and hold his ceremonial robes.
Louis is now fourth in line to the British throne, behind his father, William, and his older siblings George and Charlotte.
