Singer Amy Winehouse hit the town in London last night...with a man who shares the same name as her imprisoned husband.

As Blake Fielder-Civil languishes in jail, the Grammys winner attended two London Fashion Week parties with American photographer and artist, Blake Wood.

In an attempt to downplay gossip that the two are romantically involved, Winehouse has reportedly told friends that Wood is homosexual.

On the town: Amy Winehouse hit the town last night for the first time since leaving rehab...with American photographer and artist Blake Wood

But a newspaper claimed today that Wood, who has been nicknamed 'Good Blake' because of his comparatively clean lifestyle compared with Fielder-Civil, is bisexual and has been getting increasingly close with Winehouse.

Referring to the pair's relationship, The Sun quoted a source saying: "Amy's husband wouldn't be happy if he knew how close they'd become."

There was no evidence of any romantic involvement during their night out in London yesterday, however.

And despite her new friendship, Amy is clearly still very much attached to her husband, who is currently on remand at London's Pentonville Prison after being charged with attempting to pervert the course of justice.

Her love was on full display yesterday as she told a camera crew: "I just need my husband."

Asked if how her husband is doing in prison, she said: "He's fine. He's gorgeous."

This comes days after Winehouse memorably dedicated her recent Grammy success to 'Blake my incarcerated'.

Winehouse and 'Good Blake' attended a party for the British designer Andrew Buckler, later moving on to a bash at private members club Shoreditch House.

According to The Sun, the pair hit it off after being introduced by Kelly and since Amy has been out of rehab.

The publication claimed they have been spending hours together at the Park Plaza hotel in London where she has been staying.

It was also reported that 'Good Blake' recently accompanied Winehouse to visit 'Bad Blake' behind bars.

In recent days, the singer has looked noticeably healthier, appearing groomed, with glowing skin and having appeared to have gained some weight.

Last night, she was the model of seeming sobriety as she partied for the first time since entering rehab for her spiralling drug addiction.

Her family and friends are hopeful that she is close to conquering her drug addictions.

The singer's recent Grammy appearance has clearly sparked hope among her family that she is back on the drug-free track for good.
