The singer, 26, was spared jail time after she pleaded guilty to common assault and disorder on Wednesday at Milton Keynes Magistrates' Court in Buckinghamshire, England.
She admitted she had drunk too much when she pulled theater manager Richard Pound's hair and called him an expletive after he had told her she couldn't have another alcoholic drink while attending a show before Christmas. The court was told that Winehouse had drunk five vodka and Cokes before the incident.
Dressed for court in a short grey skirt, white blouse and pink ballet pumps, Winehouse was given a two-year conditional discharge as well as ordered to pay court costs and compensation to the victim totaling $300.
Judge Peter Crabtree told Winehouse, who was charged under her married name Amy Civil, that she will be "hit hard" if she commits any further offenses within the next two years.
