Monaco’s newborn royals, Princess Gabriella and Crown Prince Jacques Honore Rainier, posed for their first official photos with their parents, Prince Albert and Princess Charlene.
The photos were released Tuesday on the royal family’s official Facebook account. They were taken at the Princess Grace Hospital, where the twins were born on December 10.
“A beautiful Christmas gift to Monaco, friends of the Principality of Monaco and the royal family,” said the post.
The twins are the first children born to Charlene Wittstock, the former South African Olympic swimmer who married Prince Albert II in 2011.
Even though Jacques was born two minutes after his sister, he will be next in line for the throne under Monaco law.
Prince Albert also has two children born out of wedlock in 1992 and 2003.
