The funeral for Kile Glover will be held Friday at Wieuca Road Baptist Church in Atlanta. Glover was the son of Tameka Foster, who was married to Usher.
Kile died Saturday at a hospital.
The Georgia Department of Natural Resources says Kile was run over July 6 by a personal watercraft on Lake Lanier, which is about 40 mile northeast of Atlanta. He suffered a major brain injury.
Before the accident, Usher had been in a legal battle with his ex-wife arising from a custody fight over the two sons they had together.
