As Prince Harry turns 31, here are 31 things you might not know about heir to the throne - from nicknames to his favourite computer game.
Prince Harry has turned 31 and will spend the day taking to the skies in the biggest gathering of Battle of Britain aircraft since the Second World War to mark the aerial conflict's 75th anniversary.
Since the moment he was born, the Prince's life has been recorded, photographed and documented. The public seemingly know everything there is to know about him.
We were there for his parents' divorce and his mother’s death. We are all aware of his will-they-won't-they relationships, his job, that one time he wore a swastika and that other time he went to Las Vagas and got his kit off.
So what don’t we know about Prince Harry? Well, here are 31 suggestions - one for every year:
1 When he started nursery school in London aged three, Prince Harry didn't automatically get on well with the other children and was reportedly picked on by bullies.
2 His kind-heartedness started early. He owned a lop-eared rabbit that lived in a hutch in the stable yard at Highgrove. The young prince would also spend hours tending to the sheep on the country estate.
3 Harry met his ex-girlfriend Cressida Bonas through his cousin Princess Eugenie in May 2012.
4 Prince Harry and Cressida Bonas are actually related, albeit very distantly. She is rumoured to be Prince Harry’s ninth cousin through King Charles II.
5 Harry had the idea for, and spearheaded, the Invictus Games: a Paralympic-style multi sport event for wounded, injured or sick servicemen and women.
6 Katy Perry is rumoured to have a crush on Prince Harry. A marriage between them would make for a hilarious Christmas gathering at the Palace, wouldn’t it? The Queen, Prince Charles and Katy Perry opening presents as she cavorts in a cupcake bra.
7 In the Army, he was known as "Captain Wales". As a British prince, he doesn’t have a fixed surname and so instead used the name of the area over which his father holds title, as a territorial suffix in place of a surname.
8 He’s a dab hand at the Fifa video game, which we know because he told the Press in an interview while out in Afghanistan, saying, "You can ask the guys, I thrash them at Fifa the whole time". Game on, Harry.
9 He will not be reading this article. Not only because obviously there’s not a lot about himself he doesn’t know, but because neither he nor William take any pleasure in reading articles about themselves and try to avoid it if they can.
10 He really hates Twitter. Poor man.
11 One of his middle names is David. The other two are Charles and Albert.
12 Aged 18, he spent his gap year in Australia and Lesotho. While in Australia, he spent time working, as his father had done, on a cattle station and participating in the Young England vs Young Australia Polo Test Match.
13 In 2007-2008 he served for 77 days in Helmand, Afghanistan. He was pulled out after the publication of the story in an Australian magazine. He returned to Afghanistan for a 20-week deployment in 2012-2013 with the Army Air Corps
14 He studied geography, art history and art at A-Level and left school with a B in art and a D in geography - enough to get him into Sandhurst.
15 He produced the documentary film The Forgotten Kingdom during his gap year in Lesotho, where he also visited Mants’ase Children’s Home near Mohale’s Hoek. Have a look this video made when he later returned to Lesotho.
16 He was educated at Eton College, famous for having graduates from the world of politics and business.
17 He has his own coat of arms, granted to him on his 18th birthday.
18 On the 10th anniversary of his mother’s death, he gave a speech at the Thanksgiving Service in which he said: "What is far more important to us now is how she is remembered as she was: fun-loving, generous, down-to-earth, entirely genuine."
19 Prince Harry also has his own monogram. It’s a lovely curly "H" with a crown on the top.
20 When commenting on the Las Vegas naked picture scandal, Prince Harry said that "at the end of the day I probably let myself down, I let my family down, I let other people down," but also that "I was in a private area and there should have been a certain amount of privacy that should have been expected." Quite right, too.
21 In an interview with NBC News, Harry said he would never stop wondering about the night that his mother died and what happened in that tunnel.
22 There was an American TV show called I Wanna Marry Harry, in which 12 women were led to believe that they were competing for Prince Harry's affections. The Harry in question was an actor, so they weren't.
23 Apparently he can fix a broken cable TV – which would come in very handy for anyone struggling to watch I Wanna Marry Harry. While visiting a temporary home in Valparaiso in Chile, he noticed a family’s TV cable wasn’t working and fixed it.
24 He supports Arsenal Football Club.
25 When he was a child, Princess Diana took William and Harry around homeless projects and Aids wards in the hope that it would give them an understanding of people’s emotions, insecurities and of people's hopes and dreams.
26 As part of the Walking With The Wounded South Pole Allied Challenge of 2013, Harry became the first member of the royal family to reach the South Pole.
27 Has named himself "the Funcle" (that's "Fun" "Uncle", for those of you wondering) of Prince George
28 When Prince Harry presented the rings at his brother’s wedding, he carried them in the cuff of his tunic as his military uniform didn’t have any pockets.
29 Prince Harry was a supporter rather than a best man during the wedding. Apparently royal weddings don’t have a best man.
30 Following training at the Royal Military Academy in Sandhurst, he was commissioned as a second lieutenant into the Blues and Royals of the Household Cavalry Regiment.
31 Harry has three medals to his name: an Operation Service Medal for Afghanistan, Queen Elizabeth II Golden Jubilee Medal and Queen Elizabeth II Diamond Jubilee Medal.
Despite talk of crumbling and chilly palaces and of Queen Elizabeth slipping down several "rich lists", Britain's monarchy will be wealthier than ever when she becomes its longest serving royal on the throne -- 63 years -- on September 9th.
