The death of Amy Winehouse’s grandmother is the reason why the troubled star is so dependent on drugs, claim the people closest to her.
Having lost her granny Cynthia in 2006 to breast cancer, the beehived singer has been in mourning since explains her former manager Nick Godwyn.
And Godwyn admits Cynthia was the only person who could control the 24-year-old's wild behaviour.
He says: "Cynthia was the one person who could make Amy behave and who she would listen to."
And Winehouse's father Mitch has backed up Godwyn's claims.
He adds: "Cynthia was more like a best friend to Amy. She kept her feet on the ground. After she went, there's nobody who she'll listen to. She certainly won't listen to me."
