Amy Winehouse has been accused of lashing out at a fan, just a week after a similar confrontation at Glastonbury.
The latest incident took place at a pub in Camden where according to victim Wayne Lindsay, the singer went wild as she hit him for no apparent reason.
Wayne has said "She was in front of me at the bar and suddenly turned and walloped me three times across the face. I couldn't believe it. I hadn't said a word to her or touched her. I was just drinking a pint with my friends.
This latest Wino drama follows a reportedly unsteady performance at the Rock in Rio festival in Madrid last week.
