Usher's eleven-year-old step-son has been declared brain dead, following a jet ski accident on Friday.

TMZ reports Kyle Glover, who is the son of Usher's estranged wife, Tameka Foster, has not experienced any brain activity since he was admitted to the hospital on Friday.

Sources say Usher arrived at the hospital on the night of July 7th, while Tameka has not left since Friday. There has been no decision yet as to whether or not he should be taken off life support.

Kyle was struck in the head by a passing jet ski while tubing on Lake Lanier in Atlanta, GA on Friday.
