Amy Winehouse wants to move house -- again

Troubled singer Amy Winehouse is set to move house for the third time in less than four months after claiming she is being tormented by "demons" in her new apartment in North London.

Amy, 24, wants to move out of the flat -- often visited by pals Mark Ronson, Kelly Osbourne & Pete Doherty -- because she feels her surroundings have contributed to her disturbed state of mind.

A source said: "She feels it is full of bad vibes and demons bringing her down."

The 'Rehab' singer quit Camden for Bow, East London, late last year to escape bad memories.

Amy then quit her home in Bow after she was filmed smoking crack there in January.

She then went back to Camden, but believes the demons followed her.
