Edoardo Mapelli Mozzi reveals what his children call the Duchess of York

Buckingham Palace announced the news earlier today, writing: "Her Royal Highness Princess Beatrice and Mr Edoardo Mapelli Mozzi are delighted to announce the safe arrival of their daughter, Athena Elizabeth Rose Mapelli Mozzi, born on Wednesday, 22^nd January, at 12:57pm, at Chelsea and Westminster Hospital, London.

"The baby was born weighing 4 pounds and 5 ounces.

"Their Majesties The King and Queen and other members of The Royal Family have all been informed and are delighted with the news."

Beatrice's mother, Sarah Ferguson, immediately took to social media to congratulate her eldest daughter.

She wrote: "Overflowing with love and joy to be able to welcome Athena Elizabeth Rose into the world.

"She is already so adored and I’m incredibly blessed to be a Granny once again.

"So proud of Edo, Beatrice and the rest of my little 5-a-side team!"

Edoardo wasted no time by commenting underneath his mother-in-law's post, writing: "The best Gigi," accompanied by a heart emoji.

The property developer implied that his three children, Wolfie, Sienna and Athena refer to the Duchess of York as "Gigi".

His eldest child, Wolfie, is from his previous relationship with American architect Dara Huang.
