Celine Dion has been "grieving" for husband who is battling throat cancer while he reveals final wish

Celine Dion's husband wants to "die in her arms".

The 'My Heart Will Go On' hitmaker's 73-year-old husband René Angélil is battling throat cancer and his final wish is to be with the singer when he passes away. Recalling their conversation, she said: "I'll say, 'You're scared? I understand. Talk to me about it.'

"And René says to me, 'I want to die in your arms.' OK, fine, I'll be there, you'll die in my arms."

However, on his instructions, she has returned to Las Vegas for her residency despite it "freaking" him out when she's not at home with him.

She added to USA Today: "Don't forget, he's been the leader of the band all my life. So it [hacks] him off to not see me all day and over here working. But he wants me to do this, do the show, do the interviews. But he freaks when I'm not home with him, too ...

"I didn't want to be here at first, I don't need it. Don't get me wrong, I love singing for people, but I have priorities. But René really gave me a gift.

"All my grieving, it was during this last year. I think I've got this. For now. When it hits me, it's going to hit me. But my biggest job is to tell my husband, we're fine. I'll take care of our kids. You'll watch us from another spot."

In the interview with ABC News, Celine told reporter Deborah Roberts how she feeds her husband through a tube as he is unable to eat normally because of the treatment.

“He can’t eat so I feed him,” she said. “He’s got a feeding tube. I have to feed him three times a day.”

The couple married in 1994 after knowing each other for 14 years.

“We are taking life one day at a time,” Celine explained in the emotional interview, which is set to air Wednesday on Good Morning America.

Celine returned to the Colosseum at Caesars Palace in late August to resume her Las Vegas residency on hiatus last summer to care for her husband.

She briefly retired to help her husband back in 1999 when he was first diagnosed.

"It is very emotional for me, and I'm anticipating the emotions to grow even more as the date gets closer," Dion told People magazine about her Vegas return.
