Amy Winehouse has been accused of calling a man a "w****r" and hitting him in the face.
The 'Rehab' singer was drinking in the Dublin Castle pub in Camden, London, when she allegedly struck out at Wayne Lindsay in an unprovoked attack.
Wayne was standing behind Amy when she suddenly spun round, screamed "w****r" at him and hit him for no apparent reason.
He said: "She was in front of me at the bar and suddenly turned and smacked me three times across the face. It really stung. I couldn't believe it. I hadn't said a word to her or touched her."
Although Wayne maintains there was no reason for Amy to become aggressive, he says she seemed very angry with him.
He said: "She was wild. She just flipped. It was as if she had voices in her head."
Security guards stepped in help but quickly realised Wayne was not at fault. Amy stormed out of the pub shortly afterwards. Wayne added to Britain's Daily Mirror newspaper: "I was really angry she thought she could get away with it. But I let it go. Amy was in no fit state to put up a fight. She looked out of it. It was as if she was in another land."
Hours later, Amy allegedly hit a fan who she claimed pinched her bottom. Just a few weeks ago, she also lashed out during her performance at the Glastonbury music festival after mistakenly believing a fan had tried to touch her trademark beehive hair style.
