In the new book Prince Charles: The Passions and Paradoxes of an Improbable Life, author Sally Bedell Smith exposed new details about Princess Diana and Prince Charles' July 1981 wedding — and included a tidbit claiming Diana uttered the wrong name at the altar!
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."
"Wedding day nerves were apparent during the ceremony. Diana mixed up the Prince's names, calling him Philip Charles Arthur George, rather than Charles Philip," the article read.
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!
