Behind-the-scenes video shows moments leading up to Celine Dion's stunning Olympics performance

Céline Dion shared an inside look at the preparations for her stunning performance at the opening ceremony of the 2024 Paris Olympics on Instagram. 

The performance of French singer Édith Piaf's "Hymne A L'Amour" was the first time Dion, 56, had performed publicly since announcing her diagnosis with stiff-person syndrome in December 2022. The rare, incurable condition has impacted Dion's ability to sing and walk, and her sister told a French publication in December 2023 that Dion no longer has full control of her muscles. 

In a previous social media post, Dion said "trying to overcome" the condition was "one of the hardest experiences" of her life.
