At one time Princess Diana and Camilla Parker Bowles were friends, but that all changed when the former found out that Camilla was having an affair with her husband. Camilla was branded public enemy No. 1 and blamed for breaking up the Prince and Princess of Wales’ marriage. After Diana’s death, the fury towards Camilla only intensified and it took years for the British public to finally accept her. Therefore, you would think Prince Charles’ current wife would be especially careful about what she does with anything once worn by the late princess. So many royal fans are appalled about what the Duchess of Cornwall did with a necklace they remember seeing on Diana.
