Marie Osmond, whose 18-year-old son Michael Blosil died Feb. 26, wants to spend more time with her family during this difficult time, her rep told TVGuide.com.

Blosil fell from a balcony in Los Angeles. One day after her son's funeral, she returned to the Flamingo stage where she's been performing with her brother, Donny. Their show will resume March 23.
