The Monaco Formula 1 Grand Prix brought out several members of the Grimaldi family this weekend. In addition to the appearance of Maria Carolina of Bourbon-Two Sicilies and Jordan Bardella in the VIP stands, where they looked very much in sync, posing for plenty of photos and showing that their unexpected romance appears to be growing stronger, Alexandre Grimaldi, Prince Albert’s son, was also spotted, along with his cousins Louis Ducruet and Camille Gottlieb, both children of Princess Stéphanie.

Cousin Bonding at the Formula 1 Track

Louis Ducruet and his wife, Marie, turned heads in the Monte Carlo paddock this weekend. Princess Stéphanie’s daughter-in-law looked effortlessly chic in a flattering powder-blue ensemble featuring tailored shorts and a short-sleeved cropped jacket, paired with a woven clutch. The couple mingled with drivers, team members, and mechanics along the track.

For the occasion, they left their daughters at home, four-year-old Victoire and one-and-a-half-year-old Constance, who have become the pride and joy of Princess Stéphanie. Once known as Monaco’s “rebel princess,” she has fully embraced her role as a devoted grandmother.

That evening, Louis and Marie made another stylish appearance at the Formula 1 gala. Marie opted for a sleek white satin gown accented with black accessories.

The couple also crossed paths with Alexandre Grimaldi, Prince Albert’s son with Nicole Coste, the former Air France flight attendant from Togo who revealed the existence of their son in 2005.

Alexandre was seen spending time with Camille Gottlieb, Louis’s sister and the youngest daughter of Princess Stéphanie and her former bodyguard, Jean-Raymond Gottlieb. Their appearance together highlighted the close bond the cousins share.

Pierre Casiraghi Makes an Appearance

Louis Ducruet was also spotted with another cousin, Pierre Casiraghi, the son of Princess Caroline of Monaco. This time, Pierre attended alone, without his wife, Beatrice Borromeo, or their children, Stefano, 9, Francesco, 8, and baby Bianca, born on October 4, 2025.

Pierre, Beatrice, and their children are well-known enthusiasts of the motorsports world. 

Last April, Pierre, Beatrice, Stefano, and Francesco attended the 15th Monaco Historic Grand Prix (baby Bianca stayed home because of her young age), where they had the opportunity to admire the legendary Ferrari driven by Jacky Ickx, widely regarded as the greatest Belgian racing driver of all time. Ickx made motorsports history with his success across multiple disciplines, including Formula racing, sports prototypes, endurance racing, and rally raids.
