“They were great children but now they’re phenomenal mothers.
“And now, I have these two exceptional grandchildren all in one year.”
Princess Beatrice and Eugenie have both given birth to their first child this year.
Princess Beatrice gave birth to a daughter, Sienna, on September 18; her first child with husband Eduardo Mapelli Mozzi.
Princess Eugenie welcomed her son, August, with husband Jack Brooksbank, on February 21.
Meanwhile she said her seven-month-old grandson August has started “smiling at her’ and appears to find her “genuinely funny”.
She offered a sweet insight into life with her grandson August.
She added: “It’s so funny because when August smiles at me now, because he’s seven and a half months, you actually know he genuinely likes you.
“It’s not a put-on smile, he genuinely finds me very funny which is quite lucky.”
The duchess has been keeping herself busy recently despite the York family newcomers, and revealed she was midway through her second Mills and Boon novel, called ‘A Discerning Lady’.
She promised that it was “more of a sweeping romance” and that there would be “more bodice ripping” than in her first novel, which was published in August, written alongside author Marguerite Kaye.
During the interview at Henley Literature Festival, she again talked about her grandchildren and her ex-husband, the Duke of York.
She said: “We all three of us keep our feet well on the ground.
“Both Prince Andrew and I feel very, very lucky.
