Sarah Ferguson has recalled how her late sister-in-law Princess Diana set her up with Prince Andrew in the 1980s.
Ferguson and Diana were close friends as teenagers, as they were fourth cousins, and the Duchess of York has told of how it was the princess who was so keen for her to go out with Andrew.
Andrew and Ferguson had met a few times over the years, but Diana was credited by the duchess as getting them together properly.
She told People: "It was Diana that said 'I need you to come and stay at Windsor and you need to be with my brother in law Andrew'.
"I remember going up to her and saying to her 'he's really cute', and her saying 'duh, Fergie'."
Ferguson, who is about to release her first novel, Her Heart for a Compass, also shared memories of the late Princess of Wales.
She said: "Every time you mention her name I smile because she had the most wonderful infectious giggle.
"The tinkling laughter is something that always melts my heart.
"There's no question she is still with us.
"She would have been so proud of her grandchildren."
She added: "She would be so proud of her boys. If she was here now, she would be working hard to have more people be inspired, have joy and have more people look at life with optimism and hope."
Diana died in 1997 at the age of 36 in a car crash in Paris.
Her 60th birthday would have been 1 July and was marked by her sons Prince William and Prince Harry, who unveiled a statue of her in the sunken garden of Kensington Palace.
The 40th anniversary of the wedding of Diana and Prince Charles is also upcoming, on 29 July.
Ferguson was married to Andrew, the Duke of York, from 1986-1992. She and the duke now both live in the Royal Lodge in Windsor.
Andrew is not currently carrying out royal duties.
Ferguson described them as "co-parents" during her interview with People TV, and also praised her daughter Eugenie as a "beautiful" mother.
Princess Eugenie and Jack Brooksbank had their first child, August, in February, and Princess Beatrice, Ferguson and Andrew's first daughter, is expecting a child in the autumn.
