The couple first announced their exciting baby news in May 2021. The new addition is Queen Elizabeth's 12th great-grandchild and the second grandchild for Sarah Ferguson and Prince Andrew. They became first-time grandparents earlier this year when Princess Beatrice's younger sister, Princess Eugenie, welcomed a son named August with husband Jack Brooksbank.
Princess Beatrice was already a stepmother to Edoardo's son Wolfie. Edoardo shares joint custody of his son with his ex Dara Huang, an architect and designer who splits her time between London and Hong Kong.

"Edo is easily one of the best dads, he is so involved, and Beatrice is already showing that she's a fantastic step-mummy," a source previously told PEOPLE. "They've been on family vacations together [with his son]. They are really happy."
Another insider previously told PEOPLE that Princess Beatrice has "embraced [Wolfie] as part of her life from the outset."

Princess Beatrice and Edoardo quietly married in July 2020 after their original wedding plans were canceled due to the coronavirus pandemic. There were about 20 close friends and family, including Beatrice's grandparents Queen Elizabeth and Prince Philip, at the ceremony at All Saint's Chapel, in Windsor Great Park — a short drive from Windsor Castle.
