Sarah Ferguson has offered her advice to Prince Harry and Meghan Markle - and said "forgiveness is key".
Fergie was speaking at an event for her new romance novel, which is released today, where she was asked about several members of the Royal Family.
As well as speaking fondly of her late mother-in-law the Queen, she also told how her former husband Prince Andrew was a "good man" and was then asked about Harry and Meghan.
The Sussexes have confirmed they have been invited to King Charles' Coronation in less than two months' time, although have yet to confirm if they will attend.
Relations between them and other royals are said to be very fractured following the publication of Harry's memoir Spare.
At the event to promote the book A Most Intriguing Lady, Fergie was asked what advice she would give the couple as well as the Prince and Princess of Wales on having a public marriage.
And she said: "I think the best way to answer that is to really take hold and lead by example. I wouldn't give advice, I would say that your actions speak louder than words."
Fergie was also very close to Harry's mother, the late Princess Diana and added that she and King Charles would be proud.
She added: "Diana and I, we played a lot and had a great time. I feel like she would be absolutely, and so is the King, so proud of their grandchildren and the family… I think forgiveness is key."
Meanwhile, elsewhere in the chat, Fergie admitted that she had not yet received an invitation to the Coronation on May 6 - unlike Harry and Meghan - and joked her attendance is "TBD".
But she shrugged it off and said: "Well I've decided the best thing about being British around a coronation - although I've never been to one - I think we should, I should set up a tea room at the bottom of the drive with bunting and cakes."
The Q&A session in New York comes days after Fergie gave another interview where she said she will "always be there" for her ex-husband Andrew.
Sarah Ferguson married the late Queen’s second eldest son in 1986 but the couple then titled the Duke and Duchess of York, split up in 1992, although they have remained friends.
She has spoken about being grateful to have "even a minute" of the Queen’s time before her death in September last year.
She told The Telegraph : “Because also, during the last three years, her poor son [Andrew] has been going through such a tumultuous time and I think HM was very relieved I could help her with him, so we became even closer then.
“I’ve always admired and adored her. Really, she was more of a mother to me than my mother.”
Asked if the Queen was confident she would be there for Andrew after her death, Sarah added: “She knew.
"I will always be there. Always. Because I love her."
