USHER'S former stepson Kile Glover died Saturday morning after being taken off life support.  He was only 11 years old.  Kile was declared brain dead just a few days after a tragic July 6th accident involving a jet ski on Lake Lanier in Georgia.  Kile and a 15-year-old female friend were floating on inner tubes when a jet ski operated by a family friend hit them.  Kile suffered a major head injury.  The girl suffered non-life threatening injuries.  An investigation is underway, but no charges have been brought yet.

Kile is the son of Usher's ex-wife Tameka.  Usher and Tameka have been involved in an ugly custody battle over their two biological sons, but when Kile was injured, Usher rushed to the hospital.  A source says, "Usher practically raised Kile as his own."
