London, Dec 10 : Troubled popstar Amy Winehouse's mother is relieved that her daughter's junkie husband Blake Fielder-Civil is back in jail.

Blake, who had recently been set free after completing 27-month jail sentence for GBH, is back in jail after he failed a drugs test and escaped.

After failing the drugs test Blake fled to the London clinic where the `Back To Black' hitmaker is being treated for a ''reaction to prescription drugs'', and begged Amy''s dad Mitch to have time with his wife.

Amy''s mum, Janis, confirmed they agreed to let the troubled star spend time with Fielder-Civil only if he then promised to go back to prison.

"Blake agreed he would turn himself in if he could see Amy, so they let him into her room. I don''t know what happened but I suppose I can imagine," The Mirror quoted Janis, as saying.

Winehouse's parents are reportedly very irate with Blake, as they think he is to be blamed for the singer's deteriorating condition.

"We''re so happy he''s back in jail. We hope he''s in there for a long time. We''re all so furious with Blake for what he''s done to Amy," Janis said.

It is also being assumed that Blake might have smuggled drugs in for Winehouse during his visit - in a bid to ruin her effort to stay clean. (ANI)
