When the UK’s Prince Charles married Diana Spencer in 1981, the whole world was watching. Literally. Aside from the 3,500 guests who came to St. Paul's Cathedral in London to watch the couple exchange vows, hundreds of millions more across the globe watched the couple wed on television. It was a storybook union, or so it seemed.
The Prince, who was 13 years his bride’s senior, had been carrying on an affair with Camilla Parker-Bowles; Charles and his wife finally divorced in 1996. In the settlement, she was awarded £17 million, the equivalent of $27 million and equal to $39 million today.
