Celine Dion is opening up about her life-altering neurological disorder ahead of the release of her documentary, “I Am: Celine Dion.”

The film, set to premiere June 25 on Prime Video, details the Quebec pop superstar’s struggle with stiff person syndrome, a progressive condition that causes muscle rigidity and painful spasms.

The 56-year-old singer revealed her diagnosis in December 2022, saying the rare illness prevented her from performing. All of her tour dates were cancelled in the months that followed.
