“He wasn’t simply referring to the fact that both were pencil-slim, dark-haired and glamorous American divorcées,” Seward noted in a reflection published by the Daily Mail.

The reported nickname takes on added weight considering the couple’s eventual decision to step down as senior royals and relocate to the United States — a move that, for some observers, mirrored Edward and Wallis’ retreat from royal life nearly a century earlier.

Nicknames have always played a curious role in royal culture, signaling everything from affection to private disapproval. King Charles and Queen Camilla, for instance, reportedly called each other “Fred and Gladys” in the early years of their courtship — a nod to characters in the BBC radio comedy The Goon Show. And, perhaps most famously, Prince Harry and Meghan named their daughter Lilibet in tribute to the Queen’s childhood nickname.

In the tight-knit and often tradition-bound world of royalty, pet names reveal more than just habit — they often speak volumes about status, sentiment, and, in some cases, unspoken tensions.
