After tragedy struck their family, Usher is offering his ex-wife Tameka Foster emotional support.

Kyle Glover, Usher's 11-year-old stepson with Foster, was declared brain dead after accidentally being hit by a jet ski on Friday, TMZ reports. He was riding an inner tube on Lake Lanier in Atlanta, GA when he was struck in the head by a passing jet ski.

Usher (real name: Usher Terry Raymond IV), 33, and Foster divorced in 2009 after two years of marriage. The couple share sons Usher Raymond V, 4, and Naviyd, 3, in addition to Kyle, Foster's son from a previous relationship.

The former spouses have recently been engaged in a heated custody dispute, but are putting that aside during this very difficult time.

"Tameka and Usher don't get along, but in this circumstance Usher is coming to her side," a source tells Us Weekly. "Usher practically raised Kyle as his own. He's known him for seven years. It is so sad what happened."
