Pop quiz for anyone who remembers season four of The Crown: A fictionalized account of the infamous ‘Balmoral Test’ plays out with a young and idealistic Princess Diana (played by Emma Corrin) enduring an unofficial examination ahead of marrying then-Prince Charles (Josh O’Connor). Spoiler alert: Diana nails it. But does this “test” actually exist? If yes, reports are swirling that Peter Phillips’ fiancée Harriet Sperling is undergoing it as we speak, joining everyone from King Charles to Kate Middleton for their annual summer retreat in the Scottish Highlands and getting a first-hand look at off-duty royal life.
