In perhaps one of the saddest revelations of Prince Harry's 60 Minutes interview with Anderson Cooper, the Duke of Sussex revealed that for 11 years he believed that his mother Princess Diana's death was a hoax and that one day she would call him and his brother Prince William and ask them to go somewhere together. She revealed that she believed it.

"For a long time I just wouldn't accept that she was gone," Harry said. 'Part of me felt that she would never have done this to us. But there was also a feeling that this was all part of the plan. (I believed she was alive.) For a while, she would call us and we would go to her."

Harry said it took him "years" to accept that his mother was really gone, adding, "I had great hope."

Diana died on August 31, 1997, from injuries sustained in an automobile accident in Paris. Harry was only 12 years old at the time, and his 13th birthday on September 15 was only about two weeks away.

According to Us Weekly, during the CBS broadcast, Harry talked about trying to see evidence of the car accident that took the lives of not only her, but also her driver, Henri Paul, and her boyfriend, Dodi Al-Fayed. The only survivor was her bodyguard, Trevor Reese-Jones, who suffered life-threatening injuries.

"I was mainly looking for evidence that she was in the car," Harry said. 'Evidence that she was injured and evidence that the paparazzi who followed her into the tunnel were taking pictures of her half-dead in the back seat [of the car]. The pictures showed photographers taking pictures through the window, and it was them in the window."

Harry's private secretary stopped looking at the more gruesome images.

"All I saw was the back of my mother's head, slumped over in the back seat. 'I will forever be grateful to him for denying me the pain that seeing it caused me. That was something that will stay with me forever."
