Camilla tied the knot with Charles, 2005   

On April 9, 2005, Camilla Parker Bowles, Duchess of Cornwall, finally tied the knot with British Prince Charles, after a relationship that spanned more than three decades since they first met in 1970. Camilla is publicly known as "the other woman" in Charles' life and has been blamed for playing an important role in wrecking the marriage between Charles and late Lady Diana Spencer. It's been said that Charles remained close to Camilla, even after his marriage to Diana in July 1981. Their affair was revealed through a tape in 1992.

It seems as though the British royal family gravitates towards scandals. Camilla once jokingly mentioned to Charles that "her maternal great-great-grandmother, Alice Keppel, was the long-time mistress of Charles' great-great-grandfather, Edward VII." In 2004, a book, entitled "Philip & Elizabeth: Portrait of a Marriage", claimed by citing the words of Sacha, Duchess of Abercorn that Philip, Duke of Edinburgh, and her maintained a "passionate friendship" for more than 20 years between 1960s and 1980s.
