Sarah Ferguson is set to 'answer questions about Prince Harry and Meghan Markle' in an upcoming interview in New York to promote her latest book.
The Duchess of York, 62, who will make an appearance at the cultural centre 92nd Street on March 6, will also speak about her relationship with the late Queen, according to the press release.
Her novel - A Most Intriguing Lady - draws on historical characters and biographical events from the duchess' royal life and family lineage.
From 1986 to 1996, 'Fergie' was married to Prince Andrew - who has been under public scrutiny in recent times due to his close relationship with convicted sex offender Jeffrey Epstein.
Despite their split, she still lives with the King's scandal-hit brother at his Royal Lodge home on the Windsor Estate.
The new book tour comes after the duchess released a saucy novel - Her Heart for a Compass - with publishers Mills & Boon just last year.
She admitted her book about an ancestor "drew on many parallels" from her own romantic experiences.
And when she found out about her great-great-aunt, Lady Margaret Montagu Douglas Scott, her "imagination took over" and she "invented a history for her".
The Duchess also revealed during an interview at the Henley Literary Festival in October that writing for the novel helped her cope with the public scrutiny around her ex-husband, as she threw herself into her work.
"I escape in life into everything through my imagination and through my will to be joyous," Sarah said, according to The Times.
Meanwhile, the royal has recently spoken publicly to deliver a tribute to her 'sissie' Lisa Marie Presley at her funeral on January 31, where she recited the wise words of Queen Elizabeth II.
Ms Ferguson said: "Sissie, this is for you with affection. My late mother-in-law used to say 'That nothing can be said, can begin to take away the anguish and the pain of these moments because grief is the price we pay for love', and how right she was.
"Today we talk about Lisa Marie. We look at Priscilla, as a mother to Lisa Marie. We look to Lisa Marie and say you lost a son. Mothers losing children, there are no words for it.
"So, today we talk about action and action is the way we can go forward, we can light the flame, so for Riley, Harper and Finley, and for the entire family, we march forward in support of you, all of us are with you and we will help you as best we can. If you just put out your hand, we will be there."
