Amy poses as cat to communicate with Blake

Amy Winehouse is posing as her cat to send secret messages to Blake Fielder-Civil.

The 'Rehab' singer has created a profile for her pet feline Shirley on social networking site Facebook and is using it to talk to her estranged husband, whom she is in the process of divorcing.

In a series of bizarre messages, Winehouse refers to Fielder-Civil – who is in rehab in Yorkshire, north England – as 'Sailor', known to be one of her nicknames for him.

Last night the cat's status read "Shirley loves Sailor".

The couple were granted a decree nisi - a preliminary stage of divorce which will become absolute next month - in the Family Division of London's High Court on July 16 following the breakdown of their troubled two-year marriage.

At the time, Winehouse's spokesman said: "She is ready to move on following the end of the marriage. Amy has not had any contact with Blake for months and is focusing on the future. She is finishing her album and in good health."
