Kyle Glover, 11, the stepson of R&B singer Usher, remained hospitalized after an accident that left him brain-dead, according to multiple reports.
The boy was struck by a personal watercraft in Atlanta on Friday, according to TMZ. The website reported he has not had any brain activity since he entered the hospital.
Kyle is the son of Tameka Foster, a personal stylist and ex-wife of the singer, whose full name is Usher Raymond. The two were married in 2007 and divorced in 2009.
Usher and Foster have been in a much publicized custody battle over their two children, Usher Raymond V and Naviyd.
Despite this heated battle, Usher has been by Foster's side in the hospital, according to reports. He chartered a jet so Foster could fly to be by her son's side, E! reported.
On Sunday, Foster posted a message to her son on her Facebook page: "Kyle, You are strong . . . You'll be saved I know it. I love you my baby. I need all #Prayers for my son! thanks you everybody!"
Kyle reportedly was on an inner tube on Lake Lanier when he was struck in the head by a personal watercraft, E! News reported. A 15-year-old girl with him was treated for a broken arm and head injury.
The man on the personal watercraft was identified Monday as Jeffrey S. Hubbard of Atlanta, according to MTV News.
Officials have declined to speak publicly about Kyle's condition, citing privacy concerns, according to the Atlanta Journal Constitution.
