Prince Albert II, his wife Princess Charlene and their twins, Prince Jacques and Princess Gabriella, participated in the traditional picnic on Friday. The little prince and princess along with their proud parents arrived at the annual Pique Nique Monegasque, Monaco’s traditional picnic, at Antoinette Park in the European principality.

Monaco’s royal couple held the twins and posed for photographs along with other children dressed in traditional Monegasque costumes, Hello reported. The adorable prince and princess were seen wearing similar traditional outfits. Both the twins had donned Dior Christening Gowns for their baptism.

The 37-year-old princess was dressed in an off-white lace top which she paired with white trouser. She teamed her look with brown and orange strappy sandals. And Prince Albert II of Monaco, 57, was dressed in white loose-fitting trousers, a blue suit jacket, white shirt and red tie for the informal day out.

Princess Albert recently mentioned that the birth of the twins was one of the “happiest moments” of the past decade -- in addition to marrying Charlene, People reported.

Meanwhile, Charlene mentioned that the little prince, who is just 8-months-old, seemed to have “have taken on much of his father’s [character].” She added that back in July he was the “Real Boss," while the cute princess was also “developing a real little princess attitude.” And like any other girl, her little daughter loved “pink” color and she did not like to hear the word “no.”

In July 2015, the Monaco royals had hosted a glamorous garden wedding party for their nephew Pierre Casiraghi and his Italian bride Beatrice Borromeo at the Royal Palace. Later, the couple also attended the Red Cross Ball. At that event the South African born Olympian was pictured wearing an elegant one-shoulder red jumpsuit that showed off her statuesque, swimmer's physique. She completed her look with gold, strappy heels.

Earlier in July, Albert also had celebrated 10 years of his accession to the throne. At the ceremony, Charlene gave an emotional speech that was dedicated to her husband, which took the latter by surprise. She declared the royal as the “prince of her heart.”
