While Pierre, 37, was not in attendance, his wife Beatrice Borromeo, whom he married in 2015, joined her in-laws at the ball. Beatrice, who is an ambassador for Dior, stunned for the occasion wearing a red gown from the fashion house with her hair styled up in a braid crown and ponytail. She and her sister-in-law Charlotte Casiraghi were spotted sweetly holding on to each other at the 69th edition of the Bal de la Rose, which was held at the Salle des Étoiles of the Sporting Monte-Carlo.

In addition to his wife Beatrice and his sister Charlotte, Pierre's mother Princess Caroline, his brother Andrea Casiraghi and his respective wife Tatiana Casiraghi and his younger sister Princess Alexandra of Hanover joined Prince Albert and Princess Charlene of Monaco at the ball on Saturday. 

Pierre has attended the glamorous event in the past. Last year, he sported a white tux and black bow tie to the ball. While it's unclear why Pierre missed the 2025 event, it was announced last month that the Yacht Club de Monaco, which he is vice president of, will compete for the first time in the Admiral’s Cup this summer. According to the club, the initiative to enter was "spearheaded by Peter Harrison, a YCM member and owner of the Jolt boats, with the enthusiastic backing of Pierre Casiraghi."

“Peter (Harrison) is a great sailor with a great team. When he suggested that we take part in the Admiral’s Cup with the Jolt boats, I immediately accepted this incredible challenge,” Pierre, who is the founder of Team Malizia, said in a statement.

Princess Caroline's younger son added, “We have a solid training programme, high-performance boats, and a determined team. Consistency will be key: two bad races, and everything becomes complicated. We’ll have to stay focused and approach each day as a new challenge."

The club shared that the "Monegasque team will field two exceptional boats: the TP52 Jolt 3, skippered by Peter Harrison in the IRC Big Boat class, and the Carkeek 40 Jolt 6, helmed by Pierre Casiraghi." The sailing competition, organized by the Royal Ocean Racing Club, will take place from July 17 to August 1 in Cowes, on the Isle of Wight.
