Usher's ex-wife Tameka Foster was not impressed by his request to postpone court hearing of the custody battle over their two children. She accused the singer of trying to win sympathy by pretending to be affected by her son Kile Glover tragedy.

Tameka claimed her former husband's move to delay the next court hearing was "simply a transparent sham." She said "[Usher] visited Kile in the hospital only once," and he reportedly ditched the funeral of the 11-year-old boy in Atlanta on Friday, July 27.

She asked the judge to turn down his request because resolving the custody battle would help her move forward. The next hearing was scheduled for August 13.

Usher previously attempted to delay the hearing because he believed it would disadvantage her because court would not want to rule against a grieving woman. He additionally feared he could lose custody of the children, which was unfair to him.

On top of that, he proposed the postponement because he's worried it would cause "unnecessary stress and strain" for him, Tameka and their kids "in the immediate wake of this [Kile] tragedy."

Usher hasn't commented on his former wife's accusations. "Silent is golden moments like that are worth a million expressions. Not sayin much cuz I'm tryin not be #misunderstood," he recently tweeted without mentioning anything about the hearing.
