London, July 9 : Troubled singer Amy Winehouse is at it again, this time punching a guy three times in the face.
The shocked recipient of the punches, drinker Wayne Lindsay, 29, said that Winehouse turned round and punched him three times in the face as he stood behind her.
"It really stung. I couldn't believe it. I hadn't said anything to her or touched her," the Sun quoted him as saying.
After punching Lindsay in the face, the 24-year-old Back to Black singer then stormed out of the pub in Camden, North London.
According to Lindsay, who is from Cambridge, Winehouse had been downing tequila and "looked as if she was in another world".
"Someone behind her pinched her bottom and she reacted," a pal of Winehouse insisted.
This is the third time that the Rehab singer has struck someone, the second being on July 5th when she had struck a fan trying to photograph her as she returned to her home nearby.
The first time she came into the news for striking a fan, was during the Glastonbury festival last month.
