Sarah Fergusonknows she’ll be an“excellent” grandmother— but she’ll have to wait a bit longer for that day to come.

Fergie, as the Duchess of York is affectionately known, took the microphone during a party in Massachusetts over the weekend to celebrate American businessman Ernie Boch Jr.’s philanthropic work — and she took the opportunity to address some rumors that have been circulating about her family.

“Jack sells tequila for Casamigos, which we love,” the royal joked. “It makes me even more of a yummy mummy because I just drink the tequila when I go and sell it.”

“What else can I tell you? No, she’s not pregnant!” Fergie added, shooting down rumors that Eugenie and Jack are expecting their first child. “I’m just going through what the journalists say and they’re all here, so I just thought I’d fill it in.”

Even if Eugenie and Jack, who tied the knot at St. George’s Chapel in Windsor Castle this past October, are not expecting now, it likely won’t be long until they have a little one running around their Kensington Palace home.

The couple plan tostart a family “as soon as they can,”royals biographer Ingrid Seward previously told PEOPLE.
