Amy Winehouse is calling a pub landlady "mummy".

The troubled 'Rehab' singer - whose alcohol-fuelled antics have caused concern for her parents while she is staying in St. Lucia - has grown close to a woman named Marjorie who runs her favourite bar on the island, and now thinks of her as family.

A source told Britain's The Sun newspaper: "She bounds into her local, Marjorie's Beach Bar, shouting, 'Mummy! Mummy!' on a daily basis.

"She's not only close to Marjorie but also her sons. She'll spend hours in there with them."

Amy's parents - who divorced when the 25-year-old singer was young - recently released pictures of their drunken daughter slumped over while playing the drums.

They have also spoken out about her problems, saying her alcohol addiction is "killing" them.

Mitch said: "I need my daughter to be a whole person again.

"I tried it all - I said, 'Amy you've got to do this, you've got to go to this doctor, you've got to do this, you've got to do that, you're killing me, you're killing your mum.' None of it worked."

Janis added: "The need to rescue her is enormous. I just want her to be OK and I would do whatever it took to make that right.

"Amy is in denial all the time. She probably feels trapped. But I know with addiction you do not have the choice because the substance itself directs you.

"I want to say to her, 'Amy, what are you doing? Don't you know what you're doing?' But by then she has got herself on to it to help her get through and I understand that."
