“SAY WORD”Usher’s stepson declared brain dead after being hospitalized after boating accident.

Usher’s celebrity pals showed an outpour of support on Twitter following the singer’s terrible tragedy this past weekend.

The singer’s 11-year-old stepson Kyle Glover has been declared brain dead after he and a 15-year-old gal pal were admitted to a hospital following a boating accident Friday, TMZ reports.

The pair were floating on inner tubes in Georgia’s Lake Lanier Friday when a Jet Ski struck the two youngsters.

Glover, whose mother is Usher’s ex-wife Tameka Foster, was reportedly struck in the head and was knocked unconscious, according to Department of Natural Resources Sergeant Mike Burgamy.

The girl also suffered serious injuries.

Both children were immediately air-lifted to Children’s Healthcare at Egelston Hospital in Atlanta.

“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.
