Andrew Morton, royal biographer and author of the book "Meghan: A Hollywood Princess," claimed that there was a disagreement between Meghan Markle, Duchess of Sussex, and Queen Elizabeth II on the duke and duchess' wedding day (via Express). Morton shared that the queen scolded Meghan for a "tantrum" she threw over which tiara to wear.

On the day of her wedding, Meghan wore Queen Mary's Diamond Bandeau, but that may not have been her first choice. Queen Elizabeth reportedly told her she couldn't wear a more sparkly tiara. According to Page Six, Meghan wanted to wear a tiara with green emeralds on it, but she was not able to. Prince Harry, Duke of Sussex, seemed to have been upset by this information and flew into a rage. However, Queen Elizabeth stated that "recollections may vary" following the incident. However, the reason why Meghan couldn't wear the original tiara she wanted may have had a more sinister background. The tiara was said to have come from Russia and was brought into the royal family under sketchy circumstances.

Robert Lacey, author of "Battle of Brothers," shared the story. "Unconfirmed by the palace — but not denied — we were told that the queen felt that she had to say 'no' to Meghan's first choice."

"There was scandal attached," Lacey added, "...about which Tsarist princess had worn the tiara and how she had been assassinated." The queen felt that if Meghan had worn this tiara on her wedding day, it wouldn't have been seen in a positive light.
