I have to disagree with both of you. The British Royal family has always been famous in the US and around the world. Millions watched when she married Prince Charles because the heir to the throne was getting married...not because he was marrying Diana, the most famous woman on the planet. The world....and I might add, the GROOM barely knew her. It wasn't Diana that made the Royal family famous. The Royal family made HER famous when she married the heir to the throne.
I agree. It would probably have been the same no matter who Charles married- at least as far as the wedding was concerned.
Afterward, though, Diana looked like a storybook princess, and that's why the press kept coming round.
