Princess Caroline’s son, Pierre Casiraghi and his wife, Beatrice Borromeo, have welcomed a baby girl, it has been revealed. As well as their newborn daughter, the couple are already parents to two sons, eight-year-old Stefano and seven-year-old Francesco.

News of the couple’s third pregnancy was annouced earlier this year by journalist and ICON Magazine founder Inga Griese. Princess Caroline’s daughter-in-law was recently pictured attending the Dior Cruise 2026 show.

Inga uploaded a few pictures from the event to Instagram, with one picture showing a pregnant Beatrice. The couple – who have been married for 10 years – have named their newborn daughter, Bianca Carolina Marta Casiraghi.

The post read: “It was a true pleasure to meet again with the icon of beauty&brain, Beatrice Casiraghi-Borromeo @astreafilms, who is happily pregnant with a girl after two sons.”

The new baby girl is Princess Caroline’s eighth grandchild.

As well as Bianca, Stefano and Francesco, Princess Caroline is already a grandmother to Andrea Casiraghi and Tatiana’s three kids, Sacha, India and Maximilian, and Charlotte Casiraghi’s children, Raphaël Elmaleh and Balthazar Rassam.

Previously speaking about her life with Pierre and their children, Beatrice told L’Officiel in 2021: “I felt a little bit guilty when I properly got back to work but I see that our kids are happy and loving school.

“Also, my husband is a very present father, which helps a lot. Children are a constant reminder that there are infinite points of view, and also that we should try harder – to be better, to make things better.”

Also speaking of her mother-in-law, she said: “As my mother-in-law once beautifully said, traditions are the transmission of fire, not the worshiping of ashes. I like this concept very much, and I think that you can enjoy the cultural and historical implications of traditions without staying stuck in the past.”
