Usher's 11-year-old stepson has been declared brain dead by doctors following the accident Friday when he was struck by a jet ski.
Kyle Glover (son of Usher's estranged wife Tameka Foster) has not experienced any brain activity since he was admitted to the hospital. And no decision yet as to whether or not to take him off life support.
Sources say Usher arrived at the hospital last night and Tameka has not left the hospital since she got there.
Kyle was struck in the head by passing jet ski while riding on an inner tube on Lake Lanier in Atlanta, GA.
