Andrew Mountbatten-Windsor and Sarah Ferguson have been divorced since 1996, but well before their relationship ended, both parties had stepped out of their marriage. In November 1989, Ferguson met American businessman Steve Wyatt while attending the British Festival in Houston, Texas. Despite being well into her pregnancy with Princess Eugenie, Sarah started an affair with Wyatt—and even invited him to the "Dance of the Decades" at Buckingham Palace.
In his book Entitled: The Rise and Fall of the House of York, author Andrew Lownie recounts how Ferguson quickly became infatuated with the American. A source who was present at the British Festival told the author, "It was obvious that Sarah was enormously attracted to him...There was clearly a chemistry between them."
