During a psychic reading in the South African jungle, Edward shared alleged details about Diana's relationship with Paul that were not public knowledge - including a 'secret' car crash that Diana was involved in before her fatal Paris crash in 1997.
'You had a friend who passed in a vehicle accident,' John began.
Burrell's interest in the conversation rose when Edward asked, 'Were there two car accidents?'
He added: 'I'm feeling like there were two car accidents - almost like one was foreshadowing and one was tragic.'
Paul was noticeably shocked, replying: 'You couldn't possibly know that.'
The former royal butler was clearly impressed by John's supposed knowledge of Diana's second accident, telling fellow campmate and self-professed psychic Jackie Gillies that the reading was an 'incredible experience.'
'How could he know about the other traffic accident?' he asked the Real Housewives Of Melbourne star, who replied: 'Because he's speaking to spirit.'
'She was frightened that night,' Paul said, referring to the previously undisclosed vehicle accident.
'She crashed her car. She couldn't drive it. She was in the middle of nowhere. She said: 'What do I do?''
He continued: 'I said, 'You go and lock yourself in the ladies loo in the nearest hotel and I'll come and get you.' And I did. I went down at midnight and collected her and then rang the police and the Palace to say they can go and tow the car.'
