It's been an unimaginably horrific week for one of the world's most beloved singers.
Yesterday, Celine Dion's husband, Rene Angelil died of cancer, and now, doctors say her beloved brother may have just hours to live.
Like Angelil, 59-year-old Daniel Dion has been battling throat cancer.
Sources say the cancer has been spreading rapidly, and his family has been informed that it's only a matter of time.
"It looks a lot like René, he had cancer of the throat, tongue and brain," says Claudette Dion, another of the singer's 13 siblings. "Our family is very experienced."
She adds, "He is 59 years old, very young to be the end of life...We are with Daniel, day and night."
Celine has reportedly canceled all of her upcoming concerts in Las Vegas in order to be by Daniel's side and help her family with funeral arrangements once he passes.
Claudette says doctors informed the family that Daniel has just "a matter of days or hours," but adds that he could pull through for another week.
The family has made the difficult decision to discontinue the medications that were keeping him alive, and they say their top priority now is ensuring that Daniel is comfortable.
