Marie Osmond's return to the stage the day after her 18-year-old son Michael Blosil's funeral has some folks wondering: how could she return to work so soon?
Osmond offered an explanation herself when she took the stage Tuesday with her older brother, Donny, for their Las Vegas variety show, "Donny & Marie," at the Flamingo Hotel.
"The way Osmonds survive is we keep singing, and that's what we want to do tonight. I know my son would want that," she told the audience.
Michael, Osmond's son with ex-husband Brian Blosil, was found dead from an apparent suicide outside his Los Angeles apartment building on Feb. 26. Blosil, a first-year student at the Fashion Institute of Design and Merchandising, jumped to his death from his high-rise apartment building in downtown Los Angeles. He reportedly left a note in which he referred to his lifelong battle with depression.
After learning the news, Marie Osmond cancelled her show on Feb. 27 through the following week. On Monday, during an emotional ceremony in Utah attended by the extended Osmond family, Osmond laid her son to rest.
The next night she was back on stage in Las Vegas, dedicating a song to her son.
"Little did I know I would be relying on my faith, especially as much as I did this past week," she said before dedicating the song to Michael, whom she called "my angel."
Wrapped in a robe with white feathers that resembled an angel's wings, Osmond genuflected and held out her right hand as she sang.
"How she got through that I will never know," said Donny Osmond after his sister's solo performance.
"I hope you all appreciate what she's going through tonight," he said. "She's a strong woman."
Donny said Marie was strong simply for showing up.
"I just think that we need to give a big round of applause to my sister for even coming onstage tonight," Donny Osmond said after the siblings' opening number.
The crowd roared its support. "Don't do that -- I'm going to have to leave," Marie Osmond quipped.
After the show, Donny Osmond posted a message on his Twitter page: "I admire my sister. She was back on stage tonight. Did a great job, and made it through the show."
While her quick return has raised some eyebrows, getting back to work may have been the best thing for Marie Osmond.
Osmond declined to comment for this story, as did her siblings contacted by ABCNews.com.
"I think people don't recognize the comforting aspects of structure and as normal a routine as possible," clinical psychologist Randi Mozenter told ABCNews.com. "For people who have a job and a routine that gives them pleasure, it doesn't mean they are OK or not grieving a horrible loss, but the job gives them a sense of purpose and a reason to get out of bed in the morning."
"Some people really need to go away for a while and hibernate and some people need to get back to their routine as quickly as possible," said Mozenter, who is on staff at Barnes-Jewish Hospital in St. Louis.
Mozenter said it's dangerous for the public to assume that just because Osmond is back at work, she's avoiding dealing with her grief. "What we're seeing is a brief period of time, when she's back in role of being an entertainer," she said. "We don't know what she's doing the other hours of the day."
