It's been a hard year for Celine Dion and her family.

The "My Heart Will Go On" singer opens up in a new Yahoo News sit-down with Katie Couric about the tragic toll cancer has had on her loved ones, losing her husband, Rene Angelil, and brother Daniel Dion, just days apart, and how she broke the news to her youngest children, 5-year-old twins Nelson and Eddy.

"I asked for some books for children to help me to how to guide them through this. Especially the twins, of course," the 48-year-old singer explains. "And it kind of, like, shook me up so much. It was not my way of wanting to talk to my children."

The way she ultimately reached her children was by referencing the Pixar film, Up.

"Up saved my life," Dion reveals. "I said, 'What is the movie that Ellie died in?' And they said, 'Ellie died in the movie Up, Mom.' I said, 'That's it. Ellie,' I said. 'Well, I want you to know listen to me.' I said, 'Papa is now with Ellie.'"

Dion is very much still mourning the loss of her brother and husband of more than two decades, but credits the incredible, genuine support of her fans for compelling her to return to the stage.

"They’ve been always there. And when René passed, I was extremely touched by the fact that they were so, so there," Dion shares. "The applause that I received for the last three months were not applause of, 'Oh, Celine, we love you so much. She's gonna sing my favorite song tonight. Oh my gosh.' They were saying to me without a word, 'Are you OK? You know we're there. You know we've always been there. Are your children fine? We can't believe you're here. Are you sure you wanna do that? We love you so much.'"
