TMZ report: Usher dismisses ex-wife's custody claims

TMZ.com is reporting that Usher is firing back at his ex-wife who asked a Georgia court last month for full custody of their two kids.

Usher is insisting he's a good father who deserves to see his kids, and that he never canceled her Saks 5th Avenue credit card.

The celebrity website reported earlier that Tameka Raymond had asked for full custody, claiming Usher has continually dropped the ball as a parent by, among other things, failing to get her permission to travel with their kids and hiring nannies without her approval.

According to TMZ, Tameka also claimed Usher callously closed her Saks 5th Avenue credit card -- and now she can't take advantage of the "special benefits" the card offers.

But TMZ reports that Usher filed his own response in the ongoing custody battle, asking a judge to reject Tameka's request for full custody on grounds her allegations are false.

Usher and Raymond share joint physical custody of the kids, according to TMZ.

Raymond has also tried numerous times to get the judge to force Usher to submit to a drug test, according to TMZ. So far, no luck.
