Celine Dion is set to throw herself back into work following the tragic death of her husband René Angélil. René lost his life earlier this month (14.01.16) following a battle with throat cancer, and his family and friends will gather to pay their tributes at the Notre-Dame Basilica in Montreal in the coming weeks. But while Celine is apparently "extremely heartbroken" following her spouse's passing, she is said to be determined not to have too long off from her Las Vegas residency. She is due to be back to work on February 23, and sources close to the family say René wouldn't have wanted her to have a lengthy leave of absence from the stage. A source said: "That's what René would want. He wants her to perform and come back. He knew her better than anybody and he probably knows that's what she needs too, to perform." Celine was the primary carer for René as his health took a turn for the worse over the past year. The source added to People: "Some days he could get up and walk around the room, play with the kids. Some days he was too tired. "She didn't travel anywhere. She wanted to be with him 24/7 in case anything happened."
