As Céline Dion gears up to return to the Las Vegas stage after what will be a year-long absence, she's opening up about what she and her family have gone through since she voluntarily pulled the plug on her hugely successful residency at Caesars Palace.
"Your heart was someplace else," ABC News' Deborah Roberts suggested during an interview with the Grammy winner airing Wednesday on Good Morning America and Nightline, referring to Dion's decision to take time off.
"Oh, come on," Dion agreed, wiping away tears. "I mean, the fans, they know I'm an open book...I sing, that's the only thing I know."
The "Because You Loved Me" artist left her show last August to care full-time for husband René Angélil following his second cancer diagnosis. The 73-year-old French-Canadian pop singer turned manager has been battling throat cancer and needs a feeding tube to eat.
"He can't use his mouth, he can't eat, so I feed him," Dion revealed. "He's got a feeding tube. I have to feed him three times a day."
And she has been hands-on throughout.
"I do this myself," she acknowledged, cracking a smile. "And so I feed my husband and I feed my kids."
She and Angelil have three sons together, 14-year-old René-Charles and 4 1/2-year-old twins, Nelson and Eddy.
It was announced last week that Dion will be resuming her residence at Caesars in August with a revamped act.
"We are taking life one day at a time," Dion added, "[but] we are choosing to live."
