Amy Winehouse’s prison visits with husband Blake Fielder-Civil have reportedly been restricted after Blake failed a drugs test last week.

Until now, their visits have taken place in an open hall, allowing physical contact, but that will now change after Class A drugs turned up in one of Blake’s random tests last week.

A source told the Sun: “As a precaution, the governor has banned Amy from having any more open visits with Blake.”

“They now have to meet in a room separated by a bullet-proof glass screen.”

Blake has also been moved to an isolation wing in the prison but it is thought to be as much for his own safety as for punishment over the drug issue.
