The trio stepped out in full pomp and pageantry for Monacoโs illustrious annual event at Le Parc Princesse Antoinette.
Noticeably absent from the day was Jacqueโs twin sister, Princess Gabriella of Monaco, who was born two minutes before her little brother.
Jacques, now one, handled the solo trip exquisitely.
The darling heir apparent to the throne has taken after his South African mother.
The tiny tot shared her pretty blonder hair, sweet smile and those magnificent blue eyes!

Jacques has his mummyโs eyes.

The adorable tot is growing so quickly!
Meanwhile, the twinsโ mother and former Olympian looked radiant.
Charlene stunned in a long-sleeved cream dress, decorated with intricately embroidered flowers.
The 38-year-old completed the outfit with a pair of black heels and her signature red lip.
Her son has inherited his mamaโs style, looking very chic in a red polo teamed with white pants and tiny black sneakers.

Twinning with his mama with the same striking features!
The royal family are regular attendees of Monacoโs Picnic, with the popular event held at Le Parc Princesse Antoinette, annually.
Last year on December 10, Prince Albert and Princess Charleneโs precious cherubs celebrated their first birthday.
Already, the little tots are forming very distinctive personalities.
Speaking about her children, the South African beauty told Paris Match they were well and truly growing into their own little people.
โJacques is a real boss. Heโs grown a lot and seems to have taken after his father. He only needs a little sleep, and heโs looking around all the time,โ Charlene, who married Albert in 2011, revealed of her son.

โJacques is a real boss,โ Charlene mused.

Like daddy, Jacques is ready to get a move on with the day!
โHeโs very observant and has developed a real protective side, which he directs towards his sister Gabriella. They interact in their own little world. Itโs amazing to watch them.โ
As for her darling daughter, who was absent from the event, โWeโve noticed, funnily enough, that sheโs developing a real princess attitude. I can tell you that her favourite colour is pink and that โnoโ is a word she doesnโt like.โ
And it looks like Charleneโs eldest takes after her.
Telling People, she revealed Gabriella is the more adventurous swimmer.
โShe likes putting her head underwater more than Jacques does!โ

We canโt wait to see more of Princess Gabriella.
