Marie Osmond's teenage son committed suicide last night, this according to law enforcement.
Michael Blosil, one of Osmond's eight children, jumped from his downtown Los Angeles apartment building.
Law enforcement sources tell TMZ Michael left behind a note that said he intended to commit suicide due to a life-long battle with depression.
An autopsy will be performed and toxicology tests will be taken.
Donny Osmond released a statement that says: "Please pray for my sister and her family."
Donny and Marie canceled their show at the Flamingo Las Vegas tonight.
