Princess Diana only had a relationship with Dodi Fayed ‘to have a fun summer on his yacht’, it has been claimed.
Her private secretary Michael Gibbins said the romance was never real and would not have lasted.
The couple were killed in a car crash in Paris 20 years ago but Mr Gibbins believes their connection would have ‘disintegrated’.
Princess Diana and Dodi Fayed, pictured left and right in summer 1997 in St Tropez, were ‘not serious’ and she was only with him for ‘fun on his yacht’, according to her former private secretary
The couple would ‘only have lasted a few weeks more’ had they not been killed in a car crash in Paris in 1997, according to Mr Gibbins
He told The Sun: ‘I think frankly she was just having a lovely summer at somebody else’s expense to be perfectly honest.’
The pair were pictured enjoying fun in the sun on Mr Fayed’s boat and were even rumoured to have been shopping in Monte Carlo for an engagement ring, while others claimed she was pregnant with his child.
But Mr Gibbins said he ‘absolutely did not believe’ them and said her appearances on his yacht were because she ‘superficially enjoyed’ the lifestyle.
He told The Sun: ‘My feeling was that she was determined to build a new her in whatever way. She was probably pretty bitter and angry at the way things had turned out.’
It comes after it was revealed Diana was heard opening up about her ‘grim’ marriage split in a secret recording of a call with George Michael.
She told him the Royal Family was ‘not very loving’ in the chat about her divorce from Prince Charles.
As well as complaining about the pain of her bitter divorce battle with Prince Charles, she joined George in taking the mickey out of Sir Elton John.
Mr Gibbins, right, added he ‘absolutely did not believe’ rumours Diana was pregnant or that the couple, left in St Tropez in 1997, were going to marry
Meanwhile her strong desire to help the poor was inspired by a visit to see Mother Theresa’s home in Calcutta, newly discovered letters have shown.
After meeting with sick children in February 1992, the princess of Wales wrote a prayer and sent it to her butler Paul Burrell when she returned home.
An accompanying note said spoke of a profound awakening after praying with the nuns.
According to the Sunday Mirror, the note said: ‘Today, something very profound touched my life. I went to Mother Teresa’s home and found the direction I’ve been searching for all these years.
‘The sisters sang to me, a deeply spiritual experience and I soared to such heights in my spirit. The light shone from within these ladies, saints for want of a better word, such love came from their eyes and their touch was full of warmth.’
