Amy Winehouse Banned From No-strings Visits To Jailed Hubby

)The 'Rehab' singer can now see her 25-year-old better half from behind a glass screen with no physical contact.

The decision was made by London's Pentonville prison, where Fielder-Civil tested positive for a Class A drug, thought to be heroin.

Fielder-Civil is currently on remand for alleged assault and conspiracy to pervert the course of justice.

A source has revealed that the move was made as a precaution.

"As a precaution, the governor has banned Amy from having any more open visits with Blake," The Sun quoted the source, as saying.

"They now have to meet in a room separated by a bullet-proof glass screen," the source added.

A pal has revealed that Winehouse gets paranoid every time she goes to visit her husband.
