After being hit by a jet ski yesterday in Georgia, Usher's 11-year-old stepson Kile Glover has been declared brain dead, TMZ reports.

Glover, the son of Usher's ex-wife, Tameka Foster, has apparently not experienced any brain activity since the accident, which took place in Lake Lanier. The boy had been riding in an inner tube when he was struck in the head by the jet ski, and he was pulled from the water unresponsive.

According to the gossip site, Usher chartered a plane yesterday so that Foster, who had been out of town, could return to Atlanta and be at her son's bedside. The R&B star also arrived at the hospital last night, TMZ reports.

As per TMZ, the family has not yet decided whether to take Glover off of life support.
