Céline Dion made an unexpected appearance at L'Oréal Paris' annual fashion show titled Express Your Worth during the first day of the Spring-Summer 2027 Fashion Week. The event took place on Place Joffre, across from the Plénitude Arena, where Dion had performed in front of 30,000 spectators earlier in the week. Dressed in a sculptural black Schiaparelli dress from the autumn-winter 2026-2027 collection, Dion closed the show by singing "I'm Alive" from her album A New Day Has Come. Dion had been away from the stage for several years, having put her career on hold to focus on her battle with stiff person syndrome, a rare neurological condition that affects muscle control and can cause severe pain. Since the release of her documentary Je suis : Céline Dion in 2024, she has been working to regain her health and stage presence. In April 2024, she told Vogue France that she had dreamed of seeing the Eiffel Tower, a wish that has now been fulfilled. She appeared at the base of the monument after performing "L’Hymne à l’amour" by Édith Piaf during the Paris Olympics earlier in the year. Other notable appearances at the L'Oréal Paris show included Kendall Jenner and a surprise appearance by Céline Dion, who returned to the side of the "Iron Lady" to sing "I'm Alive." The term "Iron Lady" is often used to describe strong, determined women, and in this context, it likely refers to Dion's resilience and strength in overcoming her health challenges. The fashion show highlighted not only the latest trends but also the return of a beloved performer who has faced significant personal struggles. Dion's presence brought a sense of hope and inspiration to the event, reinforcing her status as a global icon who continues to captivate audiences despite the challenges she has faced.
