She had undergone an extraordinary rehabilitation after cleaning up her image.

But it was back to business as usual yesterday as Amy Winehouse descended on Soho for a shambolic night which ended at 4am.

The singer was with her two new best friends Damian Marley and Nas for the second night in a row.

But there was no sign of her new man Reg Traviss who is widely believed to be behind her recent transformation.

Amy, 26, began the night with a low key meal at Balans restaurant in Soho before going on to join celebrations for Marley’s 32nd birthday.

The youngest son of legend Bob Marley was hosting a private event at The Kayashi Club in Covent Garden, London, before continuing on to The Runaway Club in Holborn at 2am.

Amy, in true Winehouse style, didn’t stumble out of the club until 4am.

She emerged covered in drink stains and looking more than a little the worse for wear.

The woozy Rehab singer was then helped into her car by her security guard to make sure she didn’t stumble over.

And there were no surprises with her footwear – she had picked her favourite ballet pumps.

It may have been another stifling night in London but American rapper Nas still wore his favourite blue Adidas tracksuit.

Birthday boy Damian was also covering up in dark jeans and a Distant Relatives white zip-up jumper.

The previous night Amy attended the Nas and Damian Marley concert at the Hammersmith Apollo, where the pair were performing material from their highly acclaimed Distant Relatives album.

Amy’s new boyfriend Reg Traviss let his girl have a night out without him, as he was no where to be seen in the club.
