Rehab seems to be agreeing with Amy Winehouse if our pics of her visiting jailed husband Blake Fielder-Civil are anything to go by.

The troubled star looked healthier - and almost curvy in places - as she emerged from the Capio Nightingale clinic in north London and made her way to Pentonville Prison, where Blake is on remand.

This was a far cry from her last, pre-rehab visit, when a disheveled Amy shocked onlookers with her gaunt and unsteady appearance.

Amy's rep confirmed that the troubled singer had obtained a day-pass from rehab to visit her husband.

A source told Mail Online: "Blake has been very supportive in Amy's recovery. Their relationship remains solid and she's really looking forward to seeing him."

It's emerged that Amy was also questioned by police yesterday in connection with a video footage which appears to show her smoking crack cocaine.
