Before Princess Diana and Prince Charles announced their separation to the world, they attempted to put on a united front for the cameras. As Charles smiled for the cameras, Diana reportedly took the opportunity to upstage her husband.

During their marriage, Diana reportedly suspected Charles was having affair with Camilla Parker Bowles. Although Queen Elizabeth encouraged the couple to try to work things out, it became clear their marriage was over.

In November 1992, the couple went on a tour of South Korea where Diana did little to hide the rift in their marriage, according to Evening Standard editor, Robert Jobson. “I remember being on a visit to Korea and it was very, very clear then that the marriage was over. “She was doing her best to upstage the prince at every opportunity,” he revealed.

“I remember being on a visit to Korea and it was very, very clear then that the marriage was over. She was doing her best to upstage the prince at every opportunity.”

Jobson claimed the photos from the trip created speculation that Charles and Diana were no longer on good terms. “When he’d be arriving at an event and would shake hands with everybody in the correct procedure, she would steam ahead and ignore the dignitaries and embarrass him. It was pretty awful.”

In the Channel 5 documentary “The Royal Family at War,” the Princess of Wales’ former butler Paul Burrell revealed Diana made the most out of her last months by Charles’ side.

Although she could not voice her feelings about Charles, Burrell credited his former employer for using the media to her advantage. “I think Diana was very clever. She didn’t have a true voice, but she was able to convert her feelings in pictures,” he said.

“One look away from Charles in the car would tell the world’s media: ‘We’re not speaking,’” Burrell added.

Prince Charles and Princess Diana finalized their divorce in 1996. The Prince of Wales went on to date Camilla for several years before the two married in 2005.
