'He can't eat so I feed him through a tube': Celine Dion breaks down in tears in candid interview about nursing her husband through difficult battle with throat cancer

Celine Dion broke down in tears while opening up about her manager and husband René Angélil's battle with throat cancer. 

The 46-year-old, who took a year off to nurse her husband during his treatment, revealed has to be fed by a feeding tube. (Earlier this week, she announced she is returning to her Las Vegas residency in August.)

'He can't eat so I feed him,' Dion told ABC News reporter Deborah Roberts. 'He's got a feeding tube. I have to feed him three times a day.'

They have three sons together, René Charles, 14, and fraternal twins Eddy and Nelson, 4, whom Dion says have walked through their father's cancer battle.

'We are taking life one day at a time,' she said. '[But] we are choosing to live.'

Dion took an indefinite leave from the stage last year to care for Angélil after he was diagnosed with cancer for a second time. 

René was first diagnosed with throat cancer in 1999, and Celine also took a break at that time to help him recuperate.

The singer will resume her residency at Caesars Palace Las Vegas in late August with a new act, according to her rep.
