Celine Dion Opens Up About René Angélil's Throat Cancer, Has To Feed Him Via Tube (VIDEO)

One thing is for sure: Celine Dion loves her husband and her family.

An emotional Dion, who up until recently has been on a leave of absence from her Las Vegas residency to help take care of her husband, revealed sad, touching details about René Angélil’s battle with throat cancer on "Good Morning America."

The singer, 46, told ABC News’ Deborah Roberts that Angélil, 73, has to be fed by a feeding tube three times daily -- and she's the one doing it. She also involves their three sons in the process so they're not intimidated or scared. René-Charles is 14 and twin sons Eddy and Nelson are 4.

"He can’t eat so I feed him," a teary Dion said, with Angélil at her side. "He’s got a feeding tube. I have to feed him three times a day."

Dion also revealed that Angélil can't talk and can't swallow, but he was instrumental in getting Dion to return to her Vegas residency. She will return to the Vegas stage on August 27, 2015.

The couple has been married since 1994; they met 14 years prior to their nuptials.

"We are taking life one day at a time," Dion told Roberts. "[But] we are choosing to live."
