Like all good fairytales....Once upon a time brothers Prince William and Prince Harry got on so well that Harry was William's best man.
The two men used to laugh and chat together animatedly and as William waited for his future wife Kate Middleton in Westminster Abbey, Harry stood by his side.
As best man, Harry had to come up with the all important best man's speech and although it was never made public, his words reportedly caused both laughter and tears with amused guests.
In addition to jokes about William he told sweet stories and said their love inspired them, which caused Kate to cry.
His then-girlfriend had vetted his speech and we can reveal that there was one particular joke that didn't make the final cut.
According to royal expert Katie Nicholl, Prince Harry had initially written about his new sister-in-law's "killer legs" - risky for any bride, let alone the future Queen consort...
Needless to say Chelsea thought it to much.
In her book Harry: Life, Loss and Love, Katie said Harry asked Chelsy, who he dated on and off between 2004 and 2011, to give his speech a read over ahead of the big day.
She wrote: "She had helped Harry edit the best man's speech, sensitively advising him to take out a line about Kate’s 'killer legs' that might have embarrassed the bride."
Harry met Chelsy at school and had asked her to accompany him to Kate and William's wedding in a bid to rekindle their relationship but, in a twist of fate, the huge and lavish ceremony is what apparently confirmed her fears that royal life wasn't for her.
Journalist Angela Levin who wrote royal biography Harry: Conversations with the Prince said: "A friend revealed that seeing the enormity and pomp of the day convinced Chelsy that she and Harry had been right to separate.
"Although they had a lot in common, she saw clearly that because they came from such different worlds it could never have worked, especially as she valued her privacy and guarded it so carefully."
Chelsy has remained friends with Harry and attended his wedding to Meghan Markle last year where William got revenge on his brother with his own best man speech.
One guest later told the Sunday Times the second in line to the throne made a "filthy" joke about wet knickers in his best man speech.
Unfortunately details of the joke haven't been leaked - yet!
William also pranked his little brother at the party, nearly flooring some of the guests in the process.
Apparently Harry recently fell off a ladder while trying to change a lightbulb, so Wills tied a ladder to the back of the newlyweds' car.
