Los Angeles: Singer Usher broke down following allegations that he was a bad father.
He was at a custody hearing for his two children -- Usher Raymond V, four, and Naviyd Ely, three -- at the Atlanta court, when he began to cry, reports TMZ.com.
The 33-year-old 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 admitted he had smoked marijuana, but said he had not done so in front of the kids.
The personal attack came just hours after Usher claimed Foster spat on his current girlfriend during a row.
Usher alleged his former spouse walked to his car and she told his girlfriend - "I`m gonna kick your ass. B***h get out of the car. How dare you bring this woman into my subdivision in my house?"
"She continued to spit. At this point she pulled the door open, tried to swing at her," he said.
Usher and Tameka filed for divorce June 2009, after almost two years of marriage. She later filed court documents in Georgia asking the singer to be stripped of joint physical custody of their sons.
