Alexandra Saint Mleux made her Cannes Film Festival debut in 2025 without her then-boyfriend, Charles Leclerc, by her side. On May 13, she returned to the French Riviera as Mrs. Leclerc, wearing a 2026 Cannes Film Festival red carpet dress alongside her suited-up husband.
So much has changed for the Leclercs over the past year. The power couple just said "I do" in March, and Alexandra's custom Paolo Sebastian gown became the celebrity wedding dress to beat. (Taylor Swift is up for the challenge, no doubt.) Hardly two months later, she brought the same regal energy at the La Vie D'Une Femme premiere, in a strapless column gown once again created by her wedding dress designer.
