Amy Winehouse is set for an agonizing wait to find out if her estranged husband Blake Fielder-Civil is to become a dad - he has demanded a paternity test from his alleged lover.

Gilleen Morris is adamant she is expecting Fielder-Civil's baby after a brief fling while they were being treated at the Phoenix Futures Rehab Centre in Sheffield, England in February.

The news has reportedly devastated Winehouse - but she will have to wait for official confirmation as her estranged husband is denying Morris' allegation and demanding a DNA test to establish the truth.

His mother, Georgette Civil, says: "We need more information."

Fielder-Civil filed for divorce from Winehouse in January over allegations she had cheated on him during a sunshine break in St. Lucia.
