According to The Sun the 'Love Is A Losing Game' singer ended her short relationship with the film director during a blazing row over his intimate meetings with burlesque dancer ex-girlfriend Raven Isis Holt.
A friend of Winehouse said: "She hasn't spoken to Reg since and she's told everyone that it's over. She's pretty cut up about it, she was serious about him. Amy is confused and vulnerable."
The 26-year-old star, who is a recovering alcoholic, has also allegedly been spotted crying in the London pub owned by her parents.
The paper additionally claimed that Winehouse has been bombarded with calls from ex-husband Blake Fielder-Civil in the wake of her break-up.
