He told pals the 27-year-old’s spirit visited him three or four times at his flat close to where she died in Camden in July.
Doherty claims he saw ghostly images in his bedroom and her reflection in his windows late at night.
The Babyshambles frontman, 32, who was a friend of the Back to Black singer, says he is too frightened to return.
A pal said: “He is utterly convinced that he has seen her ghost. “A lot of people will think his visions are probably drug-induced but he claims he is clean.”
Doherty was close friends with Amy and was left devastated after her death. According to pals he was so distressed he couldn’t bring himself to go and pay his last respects.
