Donny and Marie Osmond have cancelled their remaining shows at the Flamingo Las Vegas this week.
"She needs to spend more time with her family," her rep, Alan Nierob, tells PEOPLE. "She's still processing everything and it's really rough on her."
Osmond returned to the stage March 9, following funeral services for her son, Michael Bryan. During that first show, she and Donny were greeted by a standing ovation, and Marie told the crowd, "The way Osmonds survive is we keep singing. "That's what we want to do tonight. I know my son would want that and this show is for him."
