Prince Albert and Princess Charlene celebrate twins' first National Day

Monaco’s royal family marked the principality’s National Day on Nov. 19 with a joyous reunion on the Prince’s Palace balcony in front of thousands of well-wishers. It was a special occasion for the Grimaldis as the family’s youngest members, Prince Jacques and Princess Gabriella, enjoyed the festivities for the first time. Their doting parents, Prince Albert and Princess Charlene, were all smiles as they cuddled with their 11-month-old treasures and showed them off to the adoring public.

Prior to their balcony appearance, the family attended a special mass at the Cathedral of Monaco. Princess Stephanie, Princess Caroline and her children Pierre Casiraghi, accompanied by his wife Beatrice Borromeo, and Charlotte Casiraghi sat side by side during the reflective service before continuing celebrations at the palace.

Thursday's celebrations were a more subdued affair than usual because of the recent terrorist attacks in Paris. In light of the tragedies, Prince Albert cancelled the fireworks display that typically takes place and ordered flags to be flown at half-mast on official buildings.

The outing is the first time the twins have officially been seen in public since August and showed that they are growing up fast as they approach their first birthday on Dec. 10. Indeed, Prince Albert recently revealed that Jacques and Gabriella are starting to take their first steps and trying to speak.

"They are beginning to take their first steps and trying to say little bits of words," Albert told Monaco Matin. "They really want to express themselves and I speak to them in French. In everyday life, they are very playful and curious."
