LONDON, England (CNN) -- Singer Amy Winehouse went on trial Thursday on charges that she assaulted a woman at a London charity ball last year.
Singer Amy Winehouse arrives Thursday at Westminster Magistrates' Court in London.
Winehouse pleaded not guilty to the charge of common assault in March.
The charge relates to a September incident in which Winehouse allegedly hit a fan after agreeing to pose for a photo at the ball, British media reported.
The Grammy-winning singer returned to Britain this month after spending six months on the Caribbean island of St. Lucia.
Soon afterward, a judge granted Winehouse and Blake Fielder-Civil a divorce that should be made final next month.
She arrived at court Thursday wearing a gray skirt suit and her trademark black beehive with a blond streak. She abandoned that hairstyle in favor of natural black curls during her time on St. Lucia.
Winehouse is famous for her retro, soulful R&B sound and has had a string of hits including "Rehab," "Back to Black" and "Tears Dry on Their Own."
