Despite marrying one of the richest men in the world, Hayek's toned-down ceremony was held on Valentine's Day 2009 at a City Hall in Paris, France.
The pair later held a much more opulent ceremony at Venice's opera house La Fenice. Guests wore masquerade masks when they arrived at the black-tie ceremony, while Hayek stunned in a Balenciaga wedding gown, according to People.
Pinault, who was 47 when he married Hayek, has three children from previous relationships, including his ex-wife Dorothée Lepère.
Hayek and Pinault now share a daughter, 14-year-old Valentina Paloma Pinault, and have been married for over a decade.
"When there is conflict, we put all the energy [into] solving the problem — never finding who to blame or, 'You should have done this or that.' No," Hayek told Jada Pinkett Smith on "Red Table Talk" in June 2021. "All our energy goes into, 'How do we solve this?' "
