The Royal Family

New Royal Baby on the Way!

Kate Middleton

Grace Kelly’s granddaughter Charlotte Casiraghi is pregnant, according to PEOPLE.

Charlotte Casiraghi and her fiancé Dimitri Rassam are expecting a baby.

After weeks of press speculation, Casiraghi, 31, unveiled her bump during the recent Monte Carlo International Horse Jumping events. The news comes a few months after Princess Caroline of Monaco’s eldest daughter confirmed her engagement to Rassam by wearing a diamond ring on her left hand as they attended their first official Monaco event together in March.

A source tells PEOPLE that Casiraghi is “due late this summer, early September.”

The child will be the seventh grandchild for Princess Caroline (the 62-year-old royal’s clan has welcomed two additions since April) and the second grandchild for Dimitri’s mother, glamorous French actress and former Bond girl (For Your Eyes Only) Carole Bouquet.
