It was a big day for Dion's twins, who celebrated their first birthday since their father, Rene Angelil, died in January after a long battle with throat cancer.

"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 said in a recent interview with Yahoo News. "And it kind of, like, shook me up so much. It was not my way of wanting to talk to my children."

The "Power of Love" singer revealed that she ultimately reached her children though film -- Pixar's Up in particular.

"Up saved my life," Dion admitted. "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.'"
