London, July 7 : Troubled singer Amy Winehouse was spotted lashing out at a fan outside her home, claiming that he had pinched her bottom.
Winehouse, 24, threw a punch at the man who was taking her photo, as she arrived at her flat in Camden, North London, late on Saturday July 5.
"Amy had her bottom pinched and blamed the fan taking her picture," the Sun quoted a source as saying.
"She just lashed out and clumped him. He laughed it off," the source added.
This is the second time in a week that the singer has attacked a fan.
During her performance at Glastonbury she punched a man in the front row for touching her beehive hairdo.
