Usher’s 11 year-old stepson has been declared brain dead by doctors following the accident on Friday when he was stuck by a jet ski.

Kyle Glover, son of Usher’s ex-wife Tameka Foster, has not experienced any brain activity since he was admitted to the hospital, but no decisions has been made yet whether or not to take him off life support.

Usher arrived at the hospital last night and Tameka has not left the hospital since the incident.

Glover and the 15 year-old girl pal were floating on inner tubes in Georgia’s Lake Lanier on Friday when they both were struck by a jet ski. The girl also suffered serious injuries; while both children were immediately airlifted to the Children’s Healthcare at Egelston Hospital in Atlanta.

The cause of the incident is still under investigation.

Here is a few tweets from celebrity friends of Usher Raymond and Tameka:

“Everyone PLEASE pray for Usher and Tameka’s son! This is the time they really need your prayers,” singer Fantasia tweeted Saturday.

“Praying that Usher and Tameka’s son is ok…” Russell Simmons added.
