Usher quoted his ex as threatening: "I'm gonna kick your ass. Bitch get out of the car. How dare you bring this woman into my subdivision in my house?" and added:
"She continued to spit. At this point she pulled the door open, tried to swing at her."
Foster herself has admitted under oath that she told Usher "I will f-ck you up," while Usher said here Tameka hit him and threw a plate of food at his car while he and his unnamed girlfriend drove away.
Later in his testimony, meanwhile, Usher responded to photos of him partying in Europe and allegations by Foster's attorney that he's an unfit parent by breaking down in tears.
TMZ sources say Usher admitted to marijuana use, while an objection was made to the topic of ecstasy - and the artist didn't give a clear response to whether he had ever been with his children while under the influence.
The custody trial continues today.
