Usher broke down in tears at allegations he was a bad father in an Atlanta court yesterday. The 33-year-old singer was accused of excessive partying by his ex-wife Tameka Foster'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 children, Usher Raymond V, four and Naviyd Ely, three. According to TMZ.com, Usher admitted to smoking marijuana but said he had not done so in front of the children.

The trial will continue today.
