The National Enquirer claims the Titanic songstress has been in emotional freefall since the death of husband Rene Angelil, who succumbed to cancer in January 2016 aged 73.
In a hard-hitting article, the publication claims Celine, 49, has seen her weight drop to an alarming low as a direct consequence of her low morale.
“Celine keeps saying there’s nothing wrong with her, but by now everyone’s really terrified,” one source told the publication.
“When she’s served food, she picks at it, then pushes it away.
“Her bones are sticking out, and her clothes are literally falling off her.”
Citing her punishing work routine, the insider allegedly added, “Celine is constantly on this treadmill. Maybe it takes her mind off her mourning, but her appetite is nonexistent. I don’t know how she does it!”
Celine has yet to respond to the publication's allegations.
