Amy Winehouse reportedly got into an argument with a passenger who was "giving her strange looks" on her flight home to the UK over the weekend.

The singer sllegedly hit out at another passenger on the journey from St. Lucia – where she has been holidaying for the last two months – because she thought he was "giving her strange looks".

A friend told Britain's The Sun newspaper: "Amy went wild. She thought this guy was giving her strange looks and just lost it."

The Back To Black star - sporting her trademark beehive hairdo and heavy eyeliner - looked visibly distressed as she arrived at London's Gatwick airport.

She vowed to return to the UK after her estranged husband Blake Fielder-Civil was released from jail last week.

The source added: "She was nervous about coming back and seeing Blake so it didn't take much to push her over the edge."

Despite her strained appearance, Amy was buoyant about returning home, telling reporters: "I love London more than anything in the world."

Amy, 25, is planning to move from her Camden home, in North London, to the suburb of Barnet so she can be closer to her mother in her ongoing battle against drug addiction.

A source told Britain's Daily Mirror newspaper: "Of course Amy is sad to be back to reality. But after getting her act together and staying off the drugs, she's determined to stay clean.

"Camden holds a lot of bad memories – especially the time spent there with Blake. So while she was away, her mother Janis went house-hunting on Amy's behalf looking at houses near her own."

Amy is expected to move into the £1.4 million house this week.

She has denied she has returned to the UK to reconcile with Blake, who started divorce proceedings against her from jail in January after Amy was pictured with other men while on her Caribbean holiday.

Blake - who was given a 27-month prison sentence last July for grievous bodily harm (GBH) and attempting to pervert the course of justice - has already reportedly turned down a £100,000 divorce offer.
