Prince Harry's former aunt, Sarah Ferguson, Duchess of York, has weighed in on his plans to publish a memoir after speaking out about tensions within the royal family. In a new interview with ET, Fergie -- who was married to Prince Andrew from 1986 until 1996 and released her first romance novel, "Her Heart for a Compass," on Aug. 3 -- praised both Harry and wife Duchess Meghan's forays into book publishing. "I think the fact that Meghan's written a children's book ["The Bench," which came out in June] is really good, well done her, because anyone that sits there writing a book, it's really hard," said Fergie, who's written many children's books over the years. "With Harry, I think he's got a lot to say and, really, I think [his late mother, Princess] Diana would be really proud of her sons, and their wives and the [grandkids]. And he's such a good boy, you know, I think in life there's no question that there's far too [much] judgment and there should be more compassion and support in every way on everybody," she added. "My mission statement of my charity is no race, creed, color or any other denomination -- we stand together and we fight for the right for a child to dare to dream." Harry's publisher, Penguin Random House, in July announced that the Duke of Sussex will in late 2022 release a memoir that is the "definitive account of the experiences, adventures, losses and life lessons that have helped shape him." The book will presumably cover his decision to leave his post as a senior member of Britain's royal family. Fergie's latest book, meanwhile, centers around a young woman in British society in 1820 who's facing an arranged "society" marriage before she "flees." Sarah admitted to People magazine that her experience of marrying into the royal family influenced aspects of "Her Heart for a Compass."
