Princess Diana, Prince Charles, and Camilla Shand
Prince Charles first met Camilla Shand at a polo match. Before long, a romance had blossomed, but Charles knew that his parents would never approve of the relationship because Camilla was known for dating around. When Charles was deployed overseas in 1973, he learned that Camilla was engaged to someone else.
Although Charles went on to marry Princess Diana, his relationship with Camilla never truly came to an end. "Well, there were three of us in this marriage, so it was a bit crowded," Diana said in a bombshell 1995 interview with Martin Bashir, three years after she and Charles had separated. Charles and Camilla married in 2005. His mother, Queen Elizabeth, did not attend the civil ceremony.
