Donny Osmond and sister MARIE's Las Vegas spectacular often starts late - so the sobbing PAPER ROSES singer can compose herself before facing fans.
Her concerned brother admits he often halts the show because he can't go on while his sister is struggling to psych herself up to perform for fans just three months after her depressed teenage son Michael jumped to his death from his balcony.
Osmond tells U.S. news show Entertainment Tonight, "I hear her crying and that hurts. So I tell them, 'Delay the show.'"
The siblings have a residency at the Flamingo hotel and casino in Sin City.
