Celine Dion braved her ongoing struggle with Stiff-Person Syndrome by giving an impromptu vocal performance backstage at the 2024 Grammy Awards.

Dion, who had already captivated the audience with her surprise presence to accept the Album of the Year award, pleased fans even more with a video provided by Grammy-nominated songwriter Sonyaé. The video shows Dion and Sonyaé performing a smooth and pleasant duet, her beautiful voice ringing clear and strong.

“Highlights of an ICONIC night So inspired & proud of my girls,” Sonyaé incorporated footage of SZA, Victoria Monét, and Stevie Wonder in the video commentary.

This spontaneous performance is noteworthy for Dion, who announced her diagnosis of the uncommon neurological illness in December 2022. The syndrome produces muscle rigidity and spasms, making performance more difficult. Her few public appearances since then have raised questions about her health and future career longevity.

Fans and fellow musicians alike expressed their delight and admiration on social media, with many admiring her courage and energy.

“Celine Dion just casually reminding everyone she’s a vocal powerhouse even with Stiff-Person Syndrome,” tweeted singer-songwriter Meghan Trainor. “So inspiring!”

Stiff-Person Syndrome is a degenerative autoimmune condition that has no cure; however, therapy choices can help to manage symptoms and improve quality of life. While Dion’s future performing career remains unknown, her backstage Grammys performance demonstrates her continuing brilliance and unyielding spirit. It conveys a message of hope not only for herself, but also for others suffering from chronic ailments.
