Usher's stepson, Kyle Glover, was involved in a serious boating accident on Friday and is now in critical condition. The 11-year-old was riding an inner tube on Lake Lanier in Georgia when it was struck by a Jet Ski. An unidentified 15-year-old girl was also riding the inner tube, and she is also in critical condition.
Usher and Tameka have been involved in an ongoing and contentious custody battle, but Usher charted a jet so Tameka could be at her son's side; both children were air-lifted to Children's Healthcare at Egelston Hospital in Atlanta.
Celeb pals like Russell Simmons and Fantasia Barrino have taken to Twitter to encourage fans to pray.
"Praying that Usher and Tameka's son is OK…," Russell Tweeted.
Fantasia posted: "Everyone PLEASE pray for Usher and Tameka's son! This is the time they really need your prayers!"
Atlanta's 11 Alive News reports that the Jet Ski was being operated by a 38-year-old man, and alcohol did not play a role in the incident. It is unclear at this time whether or not charges will be filed.
