Celine Dion is speaking out on International Stiff Person Syndrome Awareness Day.

The Grammy-winning singer, 55, took to social media on Friday (March 15) to share words of encouragement and show her appreciation to fans after being diagnosed with the rare neurological disorder in recent years.

“Today the world recognizes International SPS Awareness Day,” Dion wrote on Instagram alongside a photo of her smiling with her three sons. “As many of you know, in the fall of 2022, I was diagnosed with Stiff Person Syndrome (SPS). Trying to overcome this autoimmune disorder has been one of the hardest experiences of my life, but I remain determined to one day get back onto the stage and to live as normal of a life as possible. I am deeply grateful for the love and support from my kids, family, team and all of you!”

She continued, “I want to send my encouragement and support to all those around the world that have been affected by SPS. I want you to know you can do it! We can do it!”

Since December 2022, the “My Heart Will Go On” singer has remained largely out of the public eye due to her diagnosis with stiff person syndrome, a rare neurological disorder known for causing uncontrolled muscle spasms that make it hard to move. Dion was forced to postpone all of her 2023 tour dates, before ultimately canceling the rest of her tour entirely. Last December, her sister Claudette revealed that Celine had “no control” of her muscles.

Dion made a surprise appearance at the 2024 Grammy Awards in February, presenting the coveted album of the year tropy to Taylor Swift for Midnights. As the crowd cheered for her return to the public eye, the “Power of Love” singer applauded them right back. “Thank you all,” she said, showing no signs of weakness. “I love you right back. When I say that I’m happy to be here, I really mean it from my heart.”
