LONDON, England (AP) — Amy Winehouse admits it went beyond seasonal spirit.

The singer pleaded guilty yesterday to assaulting a theatre manager who asked her to leave a family Christmas show starring Mickey Rooney because she’d had too much to drink.

The singer, whose scrapes with the law often overshadow her music, was given a fine and a warning to stay out of trouble by a judge who praised her for trying to clean up her act.

District Judge Peter Crabtree ordered Winehouse to pay her victim £185 in costs and compensation, and handed down a conditional discharge, meaning the singer will avoid further punishment as long as she does not commit any more offences for two years.

A scrum of photographers met media-magnet Winehouse as she arrived at Milton Keynes Magistrates Court, 50 miles north of London, dressed in a white shirt and dark skirt with her beehive hair piled high.

The 26-year-old singer admitted charges of disorder and common assault during a December 19 performance of the pantomime Cinderella. The petite singer had earlier admitted drinking five vodka and cola drinks before the show.

Audiences at British pantomimes — a popular form of seasonal variety show incorporating fairy-tale plots, slapstick humour, cross-dressing and music — are traditionally rambunctious and are encouraged to shout at the stage and join in with the songs. But prosecutors said Winehouse’s behaviour went beyond the usual audience participation.

Winehouse “accepted in interview that some members of the audience may have found her disorderly”, and one had asked her to be quiet, he said.

The attorney said Winehouse was moved to a private box for the second half of the show, but later left the auditorium to go to the toilet and, passing the bar, asked manager Richard Pound for a double vodka and Coke. Vickery said Winehouse felt “hurt, embarrassed and patronised” when Pound suggested she have a glass of water instead and then asked her to leave because she had had too much to drink.

He said Winehouse “with no premeditation, grabbed his hair and pulled”. She also was overheard muttering obscenities.

The judge said it was “obvious that alcohol played its part” in the incident. He said a medical report showed the singer had since tried to curb her drinking.

The singer shot to stardom with the Grammy-winning album Back to Black in 2006, but her music has been overshadowed by drug use, legal run-ins and a tempestuous marriage that ended in divorce last year. Since her divorce from Blake Fielder-Civil in July, Winehouse has kept a lower profile, spending several months in St Lucia and then moving from London’s nightlife hub of Camden to the quiet suburb of Barnet.

She recently has been back in the recording studio, raising fan hopes of a follow-up to Back to Black.
