Sherene Flash claimed the Back To Black singer lashed out at her when she asked to take a photograph after the End of Summer Ball in Berkeley Square.
The dancer said Winehouse initially agreed but as the picture was being taken she threw a punch, hitting her in the arm and cheek.
Winehouse, 25, is due to appear in court on March 17 over the incident, which took place on September 26 last year.
A spokesman for the star said: "Amy voluntarily attended a police station in London yesterday morning.
Alleged victim: Sherene Flash
"She was questioned by appointment in relation to an accusation made after the Berkeley Ball last year.
"She was charged with common assault and will attend a court hearing in the coming weeks."
Winehouse has recently come back to the UK from a two-month break in the Caribbean.
Since her return, the Grammy award winner has moved house to Hadley Wood, in Enfield, north London, from Camden.
Her husband Blake Fielder-Civil began divorce proceedings against her earlier this year.
