British singer Amy Winehouse has been charged in connection with an assault on Saturday night at a theater in Milton Keynes, police said on Wednesday.

The Grammy-award winning singer voluntarily attended a police station in the Buckinghamshire town with her lawyer on Wednesday afternoon, police said in a statement.

Winehouse, 26, was charged under the name Amy Civil, with a public order offence and common assault.

The singer won five Grammy awards in 2008 and her album Back to Black sold more than 10 million copies. But her troubled private life, including a battle against drug addiction, has overshadowed her recording success.

In July, she ended her two-year marriage to Blake Fielder-Civil.

She is due to appear at Milton Keynes Magistrates' Court on January 20, 2010.
