Princess Diana set her sights on Prince Charles years ago and made sure that she would get him. Despite their tumultuous marriage, the Princess of Wales got exactly what she wanted.

In the book “Prince Edward,” royal biographer Ingrid Seward detailed how Princess Diana first met Prince Charles. The encounter happened during the summer of 1980.

“[Prince] Edward had developed into a keen and competitive sailor and as usual was staying aboard Britannia when Diana joined the royal party as a guest of Lady Sarah Armstrong-Jones,” Seward said. “At the time, some members of the Royal Household felt that Diana had made friends with Sarah, three years her junior, in order to be invited on to the Royal Yacht,” she added.

Once Princess Diana arrived, she quickly made a beeline for the future king. The heir to the throne’s former valet and confidante, Stephen Barry, said that Princess Diana went straight to Prince Charles with a single-minded determination.

“She wanted him, and she got him,” he said. However, other royal insiders had a different take regarding the early days of the Prince and Princess of Wales’ romance.

Royal expert Tina Brown previously said that it was Camilla Parker Bowles that pushed Princess Diana as a suitable candidate for Prince Charles’ future wife. The Duchess of Cornwall also sized up the late royal and described her as the blushing little Spencer girl.

According to Brown, Prince Charles was already feeling the pressure of having to settle down from the royal family. And Camilla just added pressure on him.

“His family wanted it,” she said. “The public wanted it. Like the last Prince of Wales, he liked to confide in married women, and his two favorites, Lady Tyron and Camilla Parker Bowles, wanted it. They had met the blushing little Spencer girl and deduced she was not going to give them any trouble. Better her than another fiery member like Anna Wallace,” Brown added.

Prince Charles and Princess Diana got engaged just months after meeting each other. They tied the knot in 1981, but they divorced in 1996. In 2005, Prince Charles and Camilla tied the knot in a civil ceremony.
