Usher's ex-wife Tameka Raymond is heartbroken over her son's jet ski accident that has left him in critical condition.

The 44-year-old fashion stylist divorced from the singer three years ago and they have two children together; Usher V, four, and Naviyd, three. But Usher is said to still be close to his stepson.

Her 11-year-old son Kyle from an earlier relationship was hit in the head by a jet ski over the weekend and doctors have reportedly declared him brain dead.

"This incident was just so random there should never have been a jet ski that close to an inner tube with two young kids, it just doesn't make sense."

Kyle is currently hooked up to a life support machine in an Atlanta hospital and Tameka is using her "spirituality and devotion to God" to pull her through the friend added.

"This is a woman who lost the man of her dreams, her reputation and now her son within the course of four years," the insider said.
