Alleged drug addict Amy Winehouse stunned concert goers at the U.K.’s Glastonbury festival after seemingly attacking a fan.The rehab singer was belting out her hit track Rehab to 75,000 fans on the Pyramid Stage yesterday, when she jumped from the stage and into the high security pit. The troubled star,who has been receiving medical attention for the lung disease emphysema, then appeared to lash out at a fan, striking the unnamed devotee with her fist. But a spokesman for Winehouse insists she was provoked, adding, "The ‘lashing out’ was when someone tried to grab her hair and she reacted." Winehouse also hit back at fans who booed her as she paid tribute to her incarcerated husband Blake Fielder-Civil. She said, "Boo me one more time and I’ll find you and your phone and call your mom and tell her you ain’t got no manners."
