The princess and her fiancé, Dimitri Rassam, welcomed their first son together on Tuesday, E! reports. Casiraghi is the granddaughter of Princess Grace Kelly of Monaco and the eldest daughter of Princess Caroline of Monaco, so it's only appropriate that the baby was born at Monaco's Princess Grace hospital—named for her famous grandmother.
Rassam and Charlotte have been together since December 2016, and each have one child from previous relationships. They confirmed their engagement at an event in Monaco earlier this year, where Princess Charlotte accessorized her gown with a stunning diamond on her left hand. According to People, Rassam popped the question three weeks prior to their red carpet appearance while on a ski vacation in Austria.
Rassam is a film producer (his credits include Netflix's The Little Prince), and the couple reportedly splits their time between LA, Paris, and Monaco. It was initially rumored that they were planning a wedding in Siciliy at Rassam's mother's vineyard this past June, but reportedly put the event on hold until after the baby was born (it was initially believed that she would deliver sometime in August).
This "little prince" is actually the third baby to be born into Monaco's royal family this year. According to Hello, Charlotte's older brother, Andrea Casiraghi, and his wife, Tatiana Santo Domingo, welcomed their third child in April, and Charlotte's younger brother, Pierre Casiraghi, and his wife, Beatrice Borromeo, welcomed a son in May.

Of course, this royal baby boom also extends to the British royal family. Kate Middleton welcomed her third child with Prince William in April, and Meghan Markle and Prince Harry are expecting their first sometime next spring.
