Kile Glover, the 11-year-old stepson of singer Usher, died early Saturday morning.

Friday night Kile's mom, Usher's ex-wife Tameka Raymond, made the heart-wrenching decision to take him on life support, later tweeting out a photo of her boy, smiling broadly with one of his younger brothers.

Usher and Tameka have two sons together -- Usher V and Navlyd -- and have been engaged in a brutal custody battle. But the bitterness between the two was put on hold after Kile was in a freak accident that left him brain dead.

Usher has been a steady source of comfort to his ex since then, as she struggled with the reality of her son's terminal condition.

Kile and a friend were inner tubing on Lake Lanier when they were hit by a jet ski on July 8.  It was a family friend, who was part of the same group, who accidentally hit the pair. Officials are still investigating the accident.

Usher and Tameka's Atlanta-based friends were the first to response to Kile's death.
