The singer responded to the charges of assaulting the manager of a theatre during a Christmas show, reports Orange News.
Richard Pound said that the British songstress kicked him between his legs when he asked her to stop shouting obscenities during the performance of Cinderella on December 19.
Members of the audience complained about the star, who was shouting and swearing during the show. While trying to move Winehouse into a private suite, Pound was attacked. He filed a complaint with the Thames Valley police, and Winehouse was arrested on December 23 when she turned herself in to the authorities.
The singer has now pleaded guilty to charges of assault and disturbance. She received a conditional discharge with two years of probation and a fine of roughly $300 US.
At the end of December, Winehouse entered a treatment centre to recover from exhaustion. Just before, the star collapsed in her home in England.
