Click here for the full story, only in PEOPLE. Céline Dion might find getting back to work therapeutic while mourning the loss of her husband René Angélil. The singer is currently scheduled to take the stage at Caesars Palace in Las Vegas on Feb. 23, just weeks after Angélil’s funeral at Notre-Dame Basilica in Montreal – where the couple wed 21 years earlier. “That’s what René would want. He wants her to perform and come back,” a source tells PEOPLE. “He knew her better than anybody and he probably knows that’s what she needs too, to perform.” Angélil died on Thursday at the age of 73 and Dion is said to be “extremely heartbroken,” according to a source. Adding to the heartbreak, the singer lost her brother Daniel two days after Angélil. In the last year, Dion, 47, rarely left her husband’s side. Angélil relied on a feeding tube, and had both “good and bad days,” says the source. “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,” adds the source. “She wanted to be with him 24/7 in case anything happened.” And she was with him – Dion was at home with their three children when Angélil died.
