Pop star Usher Raymond faced fierce accusations from ex-wife Tameka Foster regarding his parenting skills in a courtroom Monday, May 21. The singer is fighting for custody of his two sons.

Fosters accused the singer of drug use and preferring to party than spend time with his children.

The “Climax” singer broke down in tears after Foster’s lawyer presented photos of him partying in Europe.

The former married couple’s relationship has turned violent with Foster admitting to telling Usher, “I will f**k you up.”

Foster fought with Usher and his girlfriend when they attempted to enter their mansion.

Usher said Foster threatened him and his girlfriend and attacked them.

He reported her saying, “I’m gonna kick your ass. B**ch 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 added.

The trial continues today.
