Marie Osmond and her family will say goodbye to young Michael Blosil in a private funeral service this Monday. A rep for Osmond, 50, confirms that the star's 18-year-old son -- he committed suicide last Friday -- will be buried March 8 in the clan's home state of Utah.
After leaving a despondent note for a friend, Blosil jumped from the eighth floor of his Los Angeles apartment building last Friday. Adopted by Osmond and her ex-husband Brian Blosil, Michael was the fifth eldest among eight kids.
Marie Osmond and her brother Donny will resume their Las Vegas show The Donny and Marie Show the following day.
A shocked, grieving friend of Michael Blosil praised his late pal to Us: "If you were sad, he would be the one to make you feel better. He would find a way to make you laugh. He was there if you needed anything."
