ATLANTA (AP) — The stepson of the Grammy award-winning pop star Usher has died, two weeks after the child was critically injured in a boating accident.

Willie A. Watkins funeral home in Atlanta confirmed Saturday it was handling funeral arrangements for 11-year-old Kile Glover. He was a son of Usher's ex-wife Tameka Foster.

The Atlanta Journal-Constitution reports (http://bit.ly/LEWGWa) that Kile died Saturday morning at an Atlanta area hospital.

The boy was run over July 6 by a personal watercraft on Lake Lanier, according to the Georgia Department of Natural Resources. He had been hospitalized with a major brain injury. Lake Lanier is about 40 miles northeast of Atlanta.

Authorities said the accident continues under investigation.

Before the accident, Usher, whose full name is Usher Raymond, had been in a legal battle with his ex-wife arising from a custody fight over the two sons they had together.

Condolences flooded social media sites late Saturday, The Atlanta Journal-Constitution reported. It said those who sent tweets of condolences included Justin Bieber, singer Toni Braxton and singer Eric Benet, among others.

Usher, long one of the top-selling singers and songwriters, has won numerous Grammy awards. He gained initial acclaim in the late 90s with albums such as "My Way" and went on to release the 10-million-plus selling 2004 album "Confessions" that firmly established him as a superstar, among several others including "Raymond v. Raymond" in 2010.
