Usher's ex-wife Tameka Foster has been denied the chance to face off against the star in court again after a judge rejected her request for a retrial in their child custody dispute. 

The singer was granted primary custody of the former couple's two sons, Usher, four, and three-year-old Naviyd, earlier this month after a bitter court battle with his ex-wife. 

Foster, who divorced the Yeah! hitmaker in 2009 after two years of marriage, refused to give up the fight and filed a motion demanding a retrial, claiming the judge overseeing the case, Superior Court Judge Bensonetta Tipton Lane, was biased because of previous campaign donations made by the singer's lawyer. 

However, the judge in Atlanta, Georgia has now denied her request, according to TMZ.com. 

The publication reports Judge Lane retorted that the re-election campaign donations had been public knowledge since 2008 and could not have factored in the custody case.
