London, July 10 : English singer songwriter Amy Winehouse shocked jail visitors with her sex act during a visit with her hubby Blake Fielder-Civil.
The incident had taken place on July 9 while the Rehab singer was visiting Fielder-Civil.
Winehouse had yanked her top down, pressed her boobs against a glass booth and writhed suggestively.
Visitors at the prison could not believe the sleazy show that was being put on by the singer in London's Pentonville, where Blake is awaiting sentence.
"It was not a pleasant sight. Amy seemed completely out of it," the Sun quoted one visitor as saying.
