Usher "Torn Up" Over Stepson's Jet Ski Accident

A family friend is under investigation and could be to blame for a jet ski accident which left Usher's 11-year-old stepson brain dead, officials revealed Monday (July 9).

The "Scream" singer's stepson, Kyle Grover, is the son of his ex-wife Tameka Foster and according to The Georgia Department of Natural Resources, Kyle was floating on an inner tube with a 15-year-old girl by a pontoon boat on Georgia's Lake Lanier when 38-year-old family friend Jeffrey S. Hubbard ran over both of them.

TMZ reports that at the time of the incident Usher had allegedly arranged for Grover to be flown to the hospital by chartering a plane. A source tells US Weekly that the 33-year-old is understandably having a hard time dealing with the tragic accident, explaining, "He grew close to Kyle and, of course, that has nothing to do with the situation with Tameka. He loved Kyle. This is a terrible, awful tragedy. Usher is torn up."

Usher's 11-year-old stepson is still in critical condition at Children's Healthcare of Atlanta, though reports confirm he's had no brain activity since being admitted. CBS Atlanta affiliate WGCL-TV reported that the boy's 15-year-old friend suffered a broken arm and cut on her head.

Although charges have yet to be filed against Hubbard, police say they are indeed pending and have confirmed that alcohol was not a factor. They also said they don't believe the watercraft malfunctioned at the time of the accident.

Usher has two children with Tameka Foster, whom he split with in 2009: Usher V, 4, and Naviyd, 3.
