Charlotte Casiraghi and Gad Elmaleh
Monaco's Charlotte Casiraghi is expecting a baby.
The 27-year-old royal and French comedian Gad Elmaleh have reportedly got engaged and will welcome their first child together into the world just before Christmas.
A source told People magazine: "Theirs is a beautiful love story and now there is a baby on the way. It's a proud moment for them."
The news comes five months after Charlotte's brother Andrea and his fiancée Tatiana Santo Domingo had their first child, with the pair expected to get married at the end of August.
Charlotte - who is the daughter of Princess Caroline and her second husband, the late Stefano Casiraghi - met France's favourite funnyman in November 2011 at the home of a mutual friend. Gad, 42, already has a 12-year-old son from a previous relationship.
The couple are rumoured to wed in a private ceremony this autumn before the baby's arrival.
The news comes as little surprise since Charlotte, a champion equestrian, was spotted with a noticeable baby bump while holidaying in Capri, Italy.
She was also seen shopping for baby clothes in a maternity shop.
