Now Prince Harry is happily married with a baby on the way, anyone looking to score a royal boyfriend will need to widen their search.
Prince Philippos of Greece and Denmark, who works as a hedge fund manager in New York, was almost as eligible as Prince Harry, but he's now taken by a private jet heiress.
There are a few other eligible gentlemen on the scene who could still fit the bill. Crown Prince Hussein bin Abdullah of Jordan is currently single. The 24-year-old heir to the throne of Jordan loves motorcycling and cooking, and was pictured earlier this year watching the England football match with Prince William on an official visit.
Prince Mateen of Brunei is sixth-in-line to the throne and unattached. The 27-year-old has a penchant for adventure sports, polo and is into exotic breeds of cat.
In the extended British royal family there's 24-year-old Louis Spencer. The University of Edinburgh graduate is set to inherit the 90-room Althorp Estate, a decision which has drawn criticism as Louis has three older sisters.
Prince Harry’s cousin and Lady Kitty Spencer’s brother isn’t officially a prince, but you'd still probably score a few royal wedding invites.
Then there's Arthur Chatto, Queen Elizabeth’s great nephew, son of her late sister Princess Margaret (who we fell in love with all over again thanks to The Crown.)
The royal is rumored to be dating fellow University of Edinburgh student Lizzie Friend. The pair were photographed at Royal Ascot over the summer and most recently posted a photo of themselves together on social media, to the distress of some of Chatto's 97k followers.
Arthur Chatto's feed makes him one of the most relaxed royals on Instagram, as he regularly posts shirtless selfies and vacation shots. We haven't seen a member of the Queen's family let their hair down so publicly since Prince Harry's infamous Vegas night out. Though we expect if Instagram had existed in Arthur's grandmother Princess Margaret's day she probably would have enjoyed a bit of scandalous over-sharing herself. The Princess did, after all, once raise eyebrows with a nude-looking 29th birthday portrait taken by her then-boyfriend Antony Armstrong-Jones.
Or there's always Arthur Chatto's arty older brother Sam Chatto - although the art-loving 22-year-old does currently have a girlfriend, a vegan blogger called Sophie Pipe. Even so, Sam still likes to flirt with his 49k followers. "Good morning beautiful" he wrote in a recent post, "yeah, I'm talking to YOU, shine bright today lovers, love Sam xxxxx".
