Céline Dion’s sister provides a bleak health update on the singer.

Céline Dion’s sister, Claudette Dion, has provided an update on the singer’s health, who was forced to cancel her world tour owing to a diagnosis of stiff person syndrome.

Céline, 55, is being cared for by their sister Linda and working closely with professional researchers for the unusual disease, according to Claudette.

“We can’t find any medicine that works, but having hope is important,” Claudette explained to SheMazing. She underlined that Céline required relaxation because she goes above and beyond during performances, always aiming for perfection.
