Marie Osmond Not in a Singing Mood After All

Singer cancels the rest of her Vegas shows for the week; assistant says she's "struggling" after son's death

Rushing back to work may not have been the best move for Marie Osmond after all.

The veteran entertainer, who resumed performing with brother Donny a day after burying her 18-year-old son, has canceled the rest of her shows at the Flamingo Las Vegas this week "to spend more time with her family," the show's producer, Chip Lightman, tells E! News.

"She worked all last week and then over the weekend and Monday," he says. "She decided she really needed more time with the family so she's taking this whole week off."

While he wouldn't say exactly where she went, Lightman promises she'll be back to work on Tuesday. But she won't be doing any promotional activities any time soon.

"Marie won't be doing interviews for quite some time," he adds.

Osmond's son Michael Bryan committed suicide by jumping from his Los Angeles apartment on Feb. 26. His family held a funeral for him March 9 in Utah.

The following night, Marie and Donny returned to the stage for an emotional performance and added six more shows in April to make up for ones they had missed.

But apparently the grieving mom could have used a little more time to rest.

Performances of Donny & Marie that were scheduled for Tuesday through Saturday this week were canceled. Their next show is March 23.
