The Canadian singer, 56, was diagnosed with the rare autoimmune neurological disorder in 2022, but has since admitted she was grappling with the condition in secrecy for nearly two decades before going public that December. She has since revealed why she was reluctant to confirm her diagnosis while secretly battling the condition for almost 17-years. Her battle with the condition will be laid bare in forthcoming documentary I AM: Celine Dion, and she discusses her reason for withholding the diagnosis in a scene from the new film.
