Watch: Prince George and Prince Louis and big rugby fans
Prince Louis is the Duke and Duchess of Cambridge's youngest child.
He was born on St George's Day, Aril 23, 2018 at the private Lindo Wing of St Mary's Hospital in Paddington, weighing 8lb 7oz, with Tower Bridge and the Golden Jubilee Bridge among London's landmarks illuminated to mark the occasion.
He was christened as Louis Arthur Charles by the Archbishop of Canterbury Justin Welby at the Chapel Royal, St James' Palace, among friends and family, and is fifth in line to the throne.
Last month, he enjoyed his fourth birthday in Norfolk with his family, after spending his second and third in lockdown. Louis has attended Willcocks Nursery School near his Kensington Palace home for more than a year.
While the prince hasn't been in seen in public much, royal fans will still remember that sweet picture his mother Kate snapped of him on his first day of school, the pantomime he enjoyed with his siblings in December 2020, and his balcony debut at Trooping of the Colour 2019 when he was only a year old.
He is next due to appear on the Buckingham Palace balcony with other members of the Royal Family, including his older sister Charlotte, seven, and older brother George, eight, at the Queen's Platinum Jubilee celebrations.
Here are some of his sweetest moments so far.

Prince Louis was photographed by Kate – who regularly releases images of her children to mark important and special occasions – laughing and enjoying himself in the dunes of Norfolk before a game of cricket.
This sweet moment marked his fourth birthday, with the images taken earlier in April.
Following in his footsteps, his great grandfather the Duke of Edinburgh was an avid cricketer and fan of the game, serving twice as the president of the Marylebone Cricket Club (MCC).
