Sarah Ferguson ‘indulged in affair in Andrew Mountbatten-Windsor’s study after he went to bed'
Fergie and Andrew's marriage proved a controversial oneSarah Ferguson reportedly had an affair in her then-husband’s study, it has been claimed.
The 66-year-old’s marriage to Andrew Mountbatten Windsor lasted 10 years, but was one mired in scandal. Now, all eyes are on the House of York again and bombshell claims are bubbling to the surface once more.

Sarah Ferguson’s ‘affair’ in Andrew’s study
In 1986, Sarah and Andrew tied the knot with an extravagant ceremony at Westminster Abbey.
However, their subsequent life as a married couple was rocky, with affair allegations rife.
They eventually divorced in 1996; however, they have been living together at the Royal Lodge for many years.
Now, new claims back up old ones that Sarah indulged in an affair right under Andrew’s nose.
In his memoir Fergie – Her Secret Life, from 1996, the ex-duchess’ former confidant Dr Allan Starkie claimed that Andrew was oblivious to his wife’s affair, despite them still sharing their marital bedroom at Sunninghill Park.
The former Duchess of York was reportedly having an affair with the American financial advisor John Bryan during her marriage to Andrew.
“When John Bryan came to stay at Sunninghill, he and Sarah would indulge in sex acts in Andrew’s study after the prince had gone to bed. She didn’t care. ‘Vulgar, vulgar, vulgar,’ stormed the Queen’s former private secretary, Lord Charteris,” the Daily Mail has claimed.

Sarah’s dressing down from Princess Anne
According to Andrew Lownie ‘s 2025 book, Entitled: The Rise and Fall of the House of York, when news of Sarah’s affair was made public, she received a dressing down from Princess Anne.
“There was not one voice raised against Anne. Andrew’s anger melted into sadness, and he buried himself in the special reports compiled for the Queen, which she did not hesitate to let him read,” he wrote.
A member of staff was also quoted as saying: “She acted in the strangest way. You would have thought she was the person wronged, as if she had every right to go on holiday with another man, kiss and cuddle him, and the only person who had behaved wrongly were the photographer and the editors of the newspapers who had published the pictures.”
Royal Insider has contacted Andrew and Sarah’s representatives, as well as Buckingham Palace.

Sarah’s plan to find ‘new love’
Now, after being handed their eviction notice by the king, it’s been reported that Sarah and Andrew are heading their separate ways.
It’s also been claimed that Sarah is hoping to find a new “love” now that she’s moving out of her ex-husband’s home.
According to insiders who have spoken to Closer magazine, Fergie has been open with friends about finding a “proper gentleman”.
However, daughter Beatrice is reportedly concerned that Sarah moving on would “crush” dad Andrew.
“Beatrice wants her mum to move on,” a source claimed. “But [she] also fears how Andrew would take it.”
The source continued, saying, “She knows her dad would be crushed. [She] fears the thought of being alone will be too much for him.”
