'Without You' singer's ex-wife claims their nanny was caught in bed with her husband.
Usher has been accused of cheating on his ex-wife with her bridesmaid.
The 33-year-old singer was questioned about sleeping with the woman during his two-year marriage to TAMEKA FOSTER during his appearance at Fulton County Court, Atlanta on Tuesday (22.05.12).
The star - whose full name is Usher Terry Raymond IV - is currently embroiled in a custody battle over his two children Usher Raymond V, four, and Naviyd Ely Raymond, three.
Apparently his lawyer objected to being quizzed about the incident involving Maya Fox Davis who used to be a nanny to their Offspring and was also involved in their 2007 wedding.
According to TMZ, he was asked if she left her work position ''because you were discovered in bed with [her].''
The trial is in recess and will be back in session in July.
Usher broke down in tears at allegations he was a bad father on Monday (21.05.12).
The 'Without You' singer was accused of excessive partying by his former partner's attorney, who showed pictures of him out at clubs while in Europe recently.
The attorney also asked him whether he took DRUGS to try and prove he was not a fit parent to stop him from getting further time with his kids.
