Last month, Dion shared more details about how difficult her life has become with stiff person syndrome, which can cause involuntary spasms and muscle rigidity, while promoting her new documentary “I Am: Celine Dion” released on Amazon.

In an interview with NBC’s Hoda Kotb at the time, the singer said trying to sing with her condition feels “like somebody is strangling you.”

The spasms can attack different parts of her body, including her abdomen, spine and ribs, she said.

“I have broken ribs at one point because sometimes when it’s very severe, it can break some ribs as well,” the Grammy-winner shared.

Dion has not allowed her diagnosis to sideline her completely however, as seen at the Grammy Awards earlier this year when she appeared onstage to present the final trophy of the evening.

In her documentary, Dion said she was determined to make her return to performing.

“If I can’t run, I’ll walk. If I can’t walk, I’ll crawl,” she said. “And I won’t stop. I won’t stop.”

CNN’s Lisa Respers France and Alli Rosenbloom contributed to this story.

This story has been updated to reflect Dion’s last performance prior to Friday was in 2020.
