A spokesman for Marie Osmond says a funeral service for the singer's 18-year-old son is set in Utah.
Publicist Alan Nierob says the service for Michael Bryan will be held Monday in a Mormon chapel near the Provo, Utah, temple. The service is private.
Police in Los Angeles have said Bryan died from an apparent suicide after jumping from the eighth floor of an apartment building on Feb. 26, 2010. An official cause of death is pending the results of an autopsy and toxicology tests.
One of five children adopted by Osmond, Bryan previously used his adoptive father's last name, Blosil. Records from Utah's 4th District Court, however, show a judge had granted the teen a petition for a legal name change.
Osmond and Brian Blosil divorced in 2007 after two decades of marriage.
