Princess Diana and Prince Charles kiss on the Buckingham Palace balcony after their wedding on July 29, 1981, in London. Diana had contended that their troubled marriage, which ended in divorce in 1996, was the result of the prince's long-term affair with Camilla Parker-Bowles, who is now Charles' second wife and the Duchess of Cornwall. Meanwhile, Diana was reportedly engaged in her own affair with a former riding instructor.
