Despite her recent stint in hospital and her father's desperate efforts to keep her in line, it appears Amy Winehouse hasn't been able to shake her bad habits.
The troubled star was seen with a white substance in her nostrils during yet another erratic night out in Camden.
She emerged from the Monarch Pub, where she had spent the evening DJing, at 2am and in typically bizarre fashion picked up a Budweiser cardboard box to hide her face as she piled into a cab.
The singer admitted in a recent interview in Rolling Stone magazine that she had taken drugs during her stay in a rehabilitation clinic, where she went to tackle her addiction to alcohol and hard drugs.
It was reported earlier this week that Winehouse's husband Blake Fielder-Civil was caught on camera doing drugs in prison.
