*The custody battle between Usher Raymond and his ex-wife, Tameka Foster, is turning into all out war, reports the New York Post.
Ursh last week rejected a demand by his ex to submit to drug testing after she alleged he was “in delirium” during a January concert in Germany.
The court drama follows a move in January by the R&B singer to obtain sole custody of their two sons, Usher Raymond V, 4, and Naviyd Ely Raymond, 2. Sources told the Post that Usher filed the motion after he asked to take the kids on his world tour and Foster refused.
In October, Foster fired back a response to Usher’s request, saying that her ex-husband has violated several provisions in their custody agreement, including not allowing Foster to see the children on Christmas last year and not paying $34,000 for nanny services.
She also filed a request for Raymond to submit to drug testing, claiming she found mysterious pills in his jeans pockets in September 2008, and that she believed he was wasted during the Germany concert, according to court documents.
Video circulated widely online at the time showing Usher meandering onstage in front of the crowd and unable to sing. He apologized to fans, and his reps blamed a respiratory infection for his inability to perform.
Foster, however, alleges he was under the influence of something. “I dated him . . . when he’s had a very serious throat condition and he still performs like a champ,” she said. “ I really feel strongly that something was going on there, and it wasn’t, ‘Oh I have laryngitis.’ ”
She made a further claim in the deposition: “I believe he gets high. And if he doesn’t then he’d take the drug test, correct?”
Usher filed a response to Foster’s allegations last week, calling Foster’s drug test request “frivolous and unfounded,” and intended to “harass and embarrass” the singer. Raymond’s lawyer, John Mayoue, declined to comment further. Foster’s lawyer, Lisa West, also declined to comment, according to The Post.
