Amy Winehouse has been found not guilty of punching a dancer at a charity ball in Berkeley Square last September.
The Jewish singer denied assaulting burlesque dancer Sherene Flash by punching her in the eye after a friend tried to jump in the photograph that Miss Flash was taking of Ms Winehouse.
She was been found not guilty at City of Westminster Magistrates' Court.
Ms Winehouse could not attend her grandmother Esther's funeral because of her trial, but mother Janis has told the Evening Standard that Ms Winehouse will attend the shiva this week after her acquittal.
District Judge Timothy Workman said both the defendant and the victim had been drunk and could not reconcile their accounts of the evening, but said he did not believe the injury was substantial enough for it to have been a serious assault.
Ms Winehouse has always insisted the incident was an accident which had spiraled out of control.
Her spokesman said: "She has always maintained her innocence and is very happy to move on with her life and put the episode behind her."
