SEE THE ROYAL PICS: Princess Charlene and Prince Albert’s twins steal the show on Monaco Day

Monaco's royals came out in full force to celebrate the principality's national day on Saturday, 19 November. 

And leading the pack of royal children were the adorable twins of their leader, Prince Albert, and his wife, Princess Charlene, who looked stunning in a chic black and white outfit.

Prince Jacques and Princess Gabriella, who turn eight on 10 December, stole the spotlight as they waved enthusiastically to the crowd from the window of the Pink Palace.

Gabby – as she’s known – looked adorable in a red dress coat and a black hat while her brother was his father’s mini-me in formal uniform. 

In a sweet Instagram post, Charlene shared a photo of the two with little Jacques saluting.

“Happy National Day,” the former SA swimmer wrote alongside the image.

This year’s holiday offered even more cause to celebrate.

For the first time in three years it went ahead smoothly following disruptions caused by the Covid-19 pandemic and then the health concerns around Charlene, which saw her unable to attend last year and her twins holding up a poignant message saying, “We miss you Mommy”.

Charlene booked herself into a Swiss facility citing emotional and physical exhaustion following a nearly year-long battle with complications stemming from an ear, nose and throat infection.

This year, however, the entire royal family assembled for the morning-long ceremonies followed by the traditional waving-from-the-palace to the crowd gathered in the square.
