Stiff Person Syndrome is a rare autoimmune and neurological condition that progressively affects the muscles in your limbs and torso.

In a post on December 8, Dion explained the condition has meant she won't be able to perform on her planned 2023 world tour, due to begin in February.

Instead it's been pushed back to 2024.

"Unfortunately, the spasms affect every aspect of my daily life sometimes causing difficulties when I walk and not allowing me to use my vocal cords to sing the way I am used to," she said in the video, where she was seen visibly upset.

"It hurts me to tell you today that this means I won’t be ready to restart my tour in Europe in February."
