A BBC retelling of the royal couple’s big day further stated Diana called her husband-to-be “Philip Charles” instead of his given name, “Charles Philip.”

Funnily enough, Diana — who sadly passed away at age 36 in an August 1997 car crash — wasn’t the only one to make a mistake during the royal nuptials. According to the BBC, Charles accidentally said “thy goods” instead of “my worldly goods” while repeating his vows. Oops!
