A friend of the late Princess Diana has spoken out to claim that Prince Charles told her that he did not love her on the eve of their 1981 wedding.

Penny Thornton, an astrologer consulted by Diana, made this claim in the new documentary The Diana Interview: Revenge of a Princess, which chronicles Diana’s infamous 1995 interview on BBC’s “Panorama.”

“One of the most shocking things that Diana told me was that the night before the wedding Charles told her that he didn’t love her,” Thornton said, according to People Magazine. “I think Charles didn’t want to go into the wedding on a false premise. He wanted to square it with her and it was devastating for Diana.”

“She didn’t want to go through with the wedding at that point, she thought about not attending the wedding,” she added.

During the 1995 interview with Martin Bashir, Diana admitted that both she and Charles were involved in affairs during their marriage. When asked if Charles’ ex-girlfriend (and current wife) Camilla Parker-Bowles contributed to their 1992 separation, Diana replied, “Well, there were three of us in this marriage, so it was a bit crowded.”

This astonishingly candid quote made headlines all over the globe.

When asked by Bashir if she had been unfaithful to Charles with British former cavalry officer James Hewitt, Diana admitted that she had been, saying, “Yes, I adored him. Yes, I was in love with him.”

In this new documentary, it is claimed that Bashir doctored bank statements to coerce Diana into speaking out. Diana’s brother Charles Spencer, the 9th Earl Spencer, spoke out earlier this month to accuse the BBC of issuing a “piecemeal apology” for the use of fake documents that were utilized to help secure the famous interview with his sister. He dismissed the findings of a 1996 BBC internal investigation that concluded that the faked papers had “no bearing” on the interview.

“[The BBC] have yet to apologize for what truly matters here: the incredibly serious falsification of bank statements suggesting that Diana’s closest confidants were spying on her for her enemies,” Spencer said.

“This was what led me to talk to Diana about such things. This in turn led to the meeting where I introduced Diana to Bashir, on 19 September 1995. This then led to the interview,” he added. “The BBC have so far refused to acknowledge the above. They claim Diana wasn’t misled. They have ignored my inquiry as to whether the apology over their false bank statements extends to the ones that actually persuaded Diana to meet Bashir.”

Rosa Monckton, a close friend of Diana’s who made the royal her daughter’s godmother, told Daily Mail that the interview contributed to Diana’s death in 1997. She said that the 1995 interview “dishonestly achieved, probably changed the course of history,” prompting Diana and Charles to begin divorce proceedings, “which meant that decisions about their future were made hurriedly, with long-term implications not thought through.”

“Among those decisions was the fact that Diana lost her royal title,” Mockton said. “Had she retained it, she would have still been in the embrace of the Royal Family when in Paris on August 31, 1997. And she would almost certainly not have been in the incapable hands of a speeding drunk driver employed by Mohamed Al-Fayed, who owned the Ritz Hotel where she and his son, Dodi, had dined.”
