The singer was introduced to Reg Traviss through a mutual friend and he owns a house just minutes away from her new home in Marylebone.
Traviss directed the 2006 film Joy Division, about a German teenager in the Second World War.
A friend said: 'Traviss has a promising career and is much more mature than Blake.'
Mr Winehouse added his approval last night when he told Scottish TV programme, The Hour, that he had already met Traviss.
He said: 'I'm happy she's moving on with her life. He's a normal bloke, very nice.'
