KUALA LUMPUR: The health of Canadian singer Celine Dion is deteriorating, and she has now lost control of her muscles.
E! Online reported recently that Celine's sister Claudette revealed that she could no longer control certain body movements, a year after revealing she was suffering from stiff-person syndrome.
"She doesn't have control over her muscles," said Claudette.
"What breaks my heart is that she has always been disciplined and always worked hard.
"Our mother always told her, you're going to do it well, you're going to do it properly."
In May, Celine, 55, cancelled her Courage World Tour due to the rare neurological disorder, which causes painful muscle spasms and stiffness.
According to Claudette, their sister Linda has been staying with Celine in Las Vegas while Celine receives treatment from doctors specialising in stiff-person syndrome.
