The "OMG!" hitmaker was on the stand for hours Monday in his ongoing custody trial with Foster and during questioning at the Atlanta court, her lawyer produced photos of the singer partying in Europe in February.
Usher is fighting for more custody of his two sons with Foster, but her lawyer tried to prove he would rather go wild at a nightclub than be a good father, TMZ reported.
Usher was also grilled about his alleged drug use. The singer admitted to smoking pot in the past, but when the subject turned to his alleged ecstasy use Usher's lawyer objected.
The singer, full name Usher Terry Raymond IV, insisted he never used drugs in front of the children -- an allegation Foster made early in their custody fight -- but hedged on the subject of seeing his children while under the influence.
