The day’s most terrible news. Unfortunately, Celine Dion confirmed it.

Céline Dion, the iconic Canadian singer, has postponed some shows on her European tour due to a new diagnosis of the uncommon neurological illness known as a stiff-person syndrome.

Dion revealed in two videos posted on her social media sites (in both English and French) on Thursday that her crippling illness prohibits her from “singing the way I’m used to.”

This is caused by stiff-person syndrome, progressive muscle rigidity, and spasm illness. People with the illness may be unable to care for themselves, handicapped, or bedridden, according to The Stiff Person Syndrome Research Foundation.
