Sarah Ferguson called her granddaughter Sienna “mini Beatrice” as she spoke of being a grandmother during a moving interview.
The Duchess of York, known as Fergie, shared the sweet nickname for the one-year-old during a sit-down chat at The 92nd Street Y in New York to promote her new novel, A Most Intriguing Lady.
The 63-year-old royal was married to Prince Andrew for 10 years before their divorce in 1996 - and they share two daughters, Princess Beatrice and Princess Eugenie.
Fergie is grandmother to Beatrice and Edoardo Mapelli Mozzi's one-year-old daughter, Sienna, and Eugenie and Jack Brooksbank's two-year-old son, August.
