Amy Winehouse appeared relaxed among friends as she partied at one of her favourite pubs in the early hours of this morning.

The troubled singer emerged from her Camden, north London home at 2.30am with her pals and the group then walked to the nearby Monarch pub.

Amy didn't leave the private lock-in until nearly three hours later at 5.15am - when witnesses report the forgetful star failed to pay for a bouquet of flowers she picked up in a petrol station forecourt.

Forgetful: Amy Winehouse reportedly failed to pay for a bouquet of flowers at a 24-hour petrol station

She may have thought a night out was in order to distract herself from worrying about her husband Blake Civil-Fielder's sentencing hearing tomorrow.

The 26-year-old is due to be sentenced for helping to beat up a pub landlord and then offering him a £200,000 bribe to buy his silence.

And, in an extraordinary move that came to light earlier today, Blake's desperate parents reportedly want him banned from seeing his 'unstable wife'.

Giles and Georgette Civil have apparently written to a crown court judge, pleading for him to order Blake to stay at the family home.

High spirits: Amy and her friends make their way home in the early hours

In an emotional interview with the News of the World, Mrs Civil, 45, said: 'Amy thinks Blake will be freed on Monday but it's not good news.

'I'm absolutely dreading it because I don't want him to go straight back to Amy.

'If he goes it could be a death sentence for the two of them.

'Blake thinks he's going to be Amy's saviour and has every intention to try to stop the drugs.

'But Amy is completely unstable. Blake is a recovering addict and he's not strong enough to resist the temptation.

'If they are reunited, I know they will be back on drugs within days.'
