The singing legend, 56, insisted such distressing scenes should not be cut from the film that chronicles her fight back to health.

I Am: Celine Dion, which aired on Prime Video from last night, sees the star tackling the progressive condition that stopped her performing.

It shows the My Heart Will Go On hitmaker moaning in agony lying on her back due to spasms, unable to move. She is attended by medical staff before recovering and singing.

Director Irene Taylor said she was thinking, "Should I film it?" when Celine went "very quickly" into the attack.

The Oscar-nominated film-maker said she continued as the singer, known for her powerful voice, had told her not "to ask permission to film something".
