The actress, 44, and husband François-Henri Pinault, 49, held on tight to their daughter Valentina’s hand as they capped off the holiday weekend with a walk on the beach.
The 3-year-old seemed in the spirit of the holiday, enjoying the beach with her parents, who wore black.
The family outing comes on the heels of news Pinault fathered a child with supermodel Linda Evangelista, who recently filed a petition in New York court seeking support from the French businessman.
