It has been formally announced this 27th day of November in the year 2017 that a British royal - Prince Henry of Wales (known to drinking buddies as Prince Harry) - is marrying an American divorcée. The last time this happened - in 1936 when King Edward VIII decided to wed American socialite Wallis Simpson — it triggered a crisis inside Windsor Castle.
