The show won't go on for Donny and Marie Osmond.

The siblings have canceled their remaining shows this week at the Flamingo Las Vegas, People magazine reports.

"She needs to spend more time with her family," Marie's rep, Alan Nierob, said. "She's still processing everything and it's really rough on her."

Marie Osmond returned to the stage March 9, following funeral services for her 18-year-old 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."

The Osmonds are expected to resume performances Tuesday.
