Amy Winehouse and Blake remarry

Amy Winehouse and Blake Fielder-Civil have sparked speculation they have remarried.

Less than two months after their divorce was finalised, the couple – who are both recovering from heroin and crack cocaine addictions - have changed their Facebook profiles to read "married".

Minutes after updating his relationship status, Blake posted a message on the social networking website reading: "Can't argue with true love. What's the point?"

The post prompted dozens of the couple's friends to write messages of congratulations on the social networking site.

The reunion is likely to infuriate the 'Back to Black' singer's father Mitch, who blames Blake for his daughter's problems with drugs and alcohol.

A family friend said: "Amy's family, especially Mitch, will be furious. They have been so happy with her progress and are terrified that if she gets back together with Blake she will fall back into drugs again."

Blake, 27, divorced Amy, 25, in July on the grounds of her infidelity.

Since then, they have been communicating via the internet, using Facebook to reminisce about their relationship and profess their love for each other.

In one rambling post, Blake - who nicknamed Amy 'Lioness' – wrote: "Love you too innit and vairvair proud of youse, know dis lioness civilishous. X (sic)."

Amy also posed as her cat to send secret online messages to Blake and weeks after their divorce, Mitch caught the couple – who married in2007 - in bed together.
