Camilla, Duchess Of Cornwall
They first met during a polo competition in 1970 and dated for a short period of time after that. Later, they separated, remarried, and had children with other people: Prince Charles married Princess Diana in front of over 750 million people around the world, while Camilla married Andrew Parker Bowles in a wedding that was much less well-publicized than the former. In spite of the fact that the two had always been in touch, allegations of an affair began to circulate in the 1980s. He and his wife divorced each other, and the duo made their first public appearance as a couple in 1999. It was 2005 when the pair were engaged, and they were married two months later.
