Usher's 11-year-old stepson, Kyle Glover, who is the son of Usher's estranged wife, Tameka Foster, is in critical condition after being struck by a jet ski at a lake, TMZ is reporting.

Kyle apparently was sitting on an intertube on Lake Lanier northeast of Atlanta when he was hit in the head by a passing jet ski. He is currently unresponsive and in critical condition at an Atlanta hospital.

TMZ reports Usher chartered a plane for Foster to be at her son's side, despite the recent drama between the two following their messy divorce.

We will update as we get more information. Our thoughts and prayers are with Usher, Tameka and their son during this time.
