Royal weddings are carefully choreographed affairs that take months of planning by teams in the hundreds, but even the most epically scheduled wedding can go wrong. Take into consideration, Prince Harry, and Meghan... Here are a few things the cameras didn't cover; enjoy! 1. Prince William Was Completely Sleep Deprived on His Wedding Day Apparently, Prince William only had a half hour of sleep before his wedding to Kate Middleton and was completely exhausted the entire day. Why? A brutal combination of nerves and screaming fans camped outside his house. "They were singing and cheering all night long, so the excitement of that, the nervousness of me and everyone singing, I slept for about half an hour," he said. Fortunately, William managed to get through his wedding day without falling asleep. Getty Images 2. Queen Elizabeth's Tiara Broke on the Morning of Her Wedding Queen Elizabeth II was given the Fringe Tiara (made in 1919 for Queen Mary) to wear when she married Prince Philip in 1947—and it broke the morning of her wedding. "The Fringe Tiara was given to Queen Elizabeth on her wedding day, and the hairdresser broke it," royal jeweler House of Garrard tells MarieClaire.com. "On that day, they had it police escorted to the House of Garrard workshops. We fixed the tiara that morning, had it sent back to Queen Elizabeth, and then she got married in it. You don't expect the Royals to have those sorts of mix-ups, but they do!" The tiara clearly survived the snafu, because Elizabeth's daughter Princess Anne wore it on her wedding day as well. (FYI, the piece can also be worn as a necklace.) Getty Images 3. Prince Charles Messed Up His Vows Prince Charles and Princess Diana's 1981 wedding had so many issues it's hard to keep track. First of all, Prince Charles messed up his vows, offering to give Diana "thy goods" (insert one million LOLs here) instead of his "worldly goods." But the real blunder came from Diana, so go ahead and swipe right to the next slide. Getty Images 4. Diana Forgot Prince Charles' Name Even more amazing than Prince Charles messing up his vows was Diana messing up her husband's name. Instead of referring to him as "Charles Philip," she called him "Philip Charles Arthur George." Which, we can all agree is completely iconic. File under: That feeling when you don't know your husband's name, lolz. 5. Princess Nathalie Forgot Her Bouquet Princess Nathalie zu Sayn-Wittgenstein-Berleburg of Denmark forgot her bouquet and had to wait almost ten minutes for it to arrive before she walked down the aisle. This is a photo of her waiting—fortunately, she doesn't look too stressed. Getty Images 6. King Harthacnut Straight Up Died at His Friend's Wedding First of all, apologies for the weird art—there are very limited options for poor King Harthacnut, who was King of England from 1040 to 1042. Anyway, this guy is basically responsible for ruining the wedding of Tovi the Proud thinks to drink too much and having a stroke. Awkward times. Getty Images 7. Diana Had an Awful Headache All Day Diana wore the Spencer Family Tiara for the duration of her wedding day, and apparently, it left her with a splitting headache. ''In the evening we all went to a sort of semi-private party," the Princess' brother Charles Spencer said. "And she was there and she seemed incredibly relaxed and happy and I just remember she had a cracking headache too because she wasn't used to wearing a tiara all morning." Getting married with a headache isn't the *worst* thing in the world, but still. Not ideal. Getty Images 8. A Horse Freaked Out During William and Kate's Wedding Apparently, a frightened horse from the Household Cavalry simply could not even when confronted with William and Kate, and freaked out as the couple traveled to Buckingham Palace. The poor horse threw its rider and ran past William and Kate, but fortunately, no one was injured, and barely anyone remembers this even happening. Getty Images 9. Marie Antoinette's Wedding Dress Was Too Small for Her Turns out Marie Antoinette's sumptuous wedding dress was made with incorrect measurements and didn't fit her. Her shift was even visible from behind! Apparently, the Duchess of Northumberland said, "the corps of her robe was too small and left quite a broad stripe of lacing and shift quite visible, which had a bad effect between two broader stripes of diamonds. She really had quite a load of jewels." Getty Images 10. Princess Diana's Dress Was Completely Wrinkled Diana's wedding dress is understandably one of the most iconic royal gowns out there (so puffy and '80s!), but no one anticipated how wrinkled it would get during the carriage ride to St. Paul's Cathedral. As you can see in this photo, the dress (and accompanying 25-foot train) was infamously rumpled. Getty Images 11. King George IV Was So Drunk at His Wedding He Had to Be Propped Up Okay, so this wedding was never going to go well. First of all, King George IV and his wife Caroline were cousins. Second of all, they'd never met prior to their engagement, and George only agreed to marry her because he was in debt. Lovely! Even worse, the King got so drunk during their wedding day that he had to be physically held up. He also burst out crying when no objections were made to the marriage. Oh, and Caroline said that on the wedding night George passed out in front of the fire. Getty Images 12. Diana's Bridesmaid Tripped and Started Crying This moment is more sweet than disastrous, but legend has it that a 5-year-old bridesmaid in Diana's wedding (who, FYI, happened to be Winston Churchill's granddaughter) tripped on her dress and started crying. Diana reportedly asked her if she'd "bumped her bottom," which is just about the most British sentence we've ever heard. Getty Images 13. Augusta of Saxe-Gotha Vomited All Over Her Mother-in-Law Poor Augusta of Saxe-Gotha. While walking down the aisle to marry Frederick Prince of Wales, she ended up vomiting all over her wedding dress, and all over her mother-in-law. No one can really blame her, considering she was 17, had just arrived in the country, didn't speak a word of English, and was marrying some random she'd never met. Getty Images 14. A Pouting Bridesmaid Photobombed William and Kate's Kiss Honestly, though, this was the best part of their wedding. Let's be real. Getty Images 15. The Wind Blew Up Lady Charlotte Wellesley's Veil When Lady Charlotte Wellesley (descendant of Queen Victoria and daughter of the Duke of Wellington) married in 2016, the wind caught her veil and lifted it sky high. She didn't seem too bothered, though, and laughed it off shortly after. Getty Images Credits: marieclaire.com Share this story on Facebook with your friends and family.
