Hewitt, not Charles, was Harry's father based on the alleged physical similarity between Hewitt and Harry, but Hewitt and others have denied this. Harry was born two years before Hewitt and Diana began their affair. By 1987, cracks in their marriage had become visible and the couple's unhappiness and cold attitude towards one another were being reported by the press, who dubbed them "The Glums" due to their evident discomfort in each other's company. In 1989, Diana was at a birthday party for Camilla's sister, Annabel Elliot, when she confronted Camilla about her and Charles's extramarital affair. These affairs were later exposed in 1992 with the publication of Andrew Morton's book, Diana: Her True Story. The book, which also revealed Diana's allegedly suicidal unhappiness, caused a media storm. In 1991, James Colthurst conducted secret interviews with Diana in which she had talked about her marital issues and difficulties. These recordings were later used as a source for Morton's book. During her lifetime, both Diana and Morton denied her direct involvement in the writing process and maintained that family and friends were the book's main source, however, after her death Morton acknowledged Diana's role in writing the tell-all in the book's updated edition, Diana: Her True Story in Her Own Words.

Philip wrote to Diana and expressed his disappointment at the extramarital affairs of both her and Charles; he asked her to examine their behaviour from the other's point of view. Philip was direct and Diana was sensitive. She found the letters hard to take, but nevertheless appreciated that he was acting with good intent. It was alleged by some people, including Diana's close friend Simone Simmons, that Diana and her former father-in-law, Prince Philip, had a relationship filled with tension; however, other observers said their letters provided no sign of friction between them. Philip later issued a statement, publicly denying the allegations of him insulting Diana. During 1992 and 1993, leaked tapes of telephone conversations reflected negatively on both Charles and Diana. Tape recordings of Diana and James Gilbey were made public in August 1992, and transcripts were published the same month. The article, "Squidgygate", was followed in November 1992 by the leaked "Camillagate" tapes, intimate exchanges between Charles and Camilla, published in the tabloids. In December 1992, Prime Minister John
