Marie Osmond

Marie Osmond told her fans that her faith is helping her get by after her son's death, according to The Associated Press.

"Little did I know I would be relying on my faith, especially as much as I did this past week," Osmond told the audience at her Las Vegas show on Tuesday.

The singer's emotional return to the Flamingo Hotel & Casino stage comes less than two weeks after her son's death and just one day after his funeral.

"I just think that we need to give a big round of applause to my sister for even coming onstage tonight," brother Donny Osmond said after their opening number.

During the show, Osmond, standing in front of a starry backdrop, wore a robe of white feathers and dedicated a song to her 18-year-old son, Michael Blosil, whom she referred to as "my angel."
