Tameka Raymond returned to court to ask the judge in their child-custody case to compel Usher to stop stalling and be tested.
TMZ.com said Sunday Raymond is seeking proof Usher has been abusing prescription drugs in front of their children and wants him tested quickly before they clear his system.
Usher has been balking on the grounds Raymond's allegations are baseless and meant to embarrass him. There was no immediate response from Usher's camp to Raymond's request.
