"He can't use his mouth, he can't eat, so I feed him," Dion, who turns 47 on Monday, told Deborah Roberts in an interview airing Wednesday night. "He's got a feeding tube. I have to feed him three times a day," she said, her voice breaking. "I do this myself. And so I feed my husband and I feed my kids."

Angélil and Dion, who married in 1994, have three sons: René-Charles, 14, and twins Eddy and Nelson, 4.
