Sarah Ferguson had nothing but nice things to say about Queen Elizabeth when she appeared on an episode of the "Tea With Twiggy" podcast.
The author became the matriarch's daughter-in-law in 1986 when she married Prince Andrew.
"I think to myself that honestly, my mother-in-law has been more of a mother to me than my mother," Ferguson confessed. "[She’s] never faltered."
The mom-of-two explained that her own mother, Susan Barrantes, was never a constant presence in her life, especially after her parents divorced in 1974. In 1998, Barrantes died in a car crash.
"I absolutely admire the incredible way Her Majesty is so modern. And how flexible, and how understanding, and how forgiving and how generous. And kind," she continued. "I absolutely think there is no greater mentor. The consistency of Her Majesty has been a great honor. A huge honor. Makes me want to cry."
When it came to raising her own children, Princess Beatrice and Princess Eugenie, the Duchess of York tried to follow by the Queen's example.
"I think the best thing I teach my girls is that you just keep being with the integrity of goodness, kindness, of humor, of being brave enough," she shared. "Eugenie has got a 12-inch metal plank down her back from having curvature of the spine with scoliosis and she wanted to show her scar at her wedding. That showed me that she had confidence and strength to do that I believe that comes from very good co-parenting between Andrew and I."
Nowadays, Ferguson is also a grandmother to Eugenie and Jack Brooksbank's 6-month-old son, August, and Beatrice and husband Edoardo Mapelli Mozzi are expecting their first child together.
