The Back To Black singer reportedly told Blake Fielder-Civil she was planning to wear her engagement ring again and the reconciled couple are now planning a wedding for three months time.
According to Britain's News of the World newspaper, Blake told a friend: "We both know we've only ever been divorced on paper. This is the right thing to do.
"We've been talking on the phone five or six times a day. On Friday she told me she was going to put the engagement ring on. It's the engagement ring I gave Amy the first time. I think it cost £2,000 (R15,000) from Tiffany."
"We'd changed our status to married on Facebook a couple of weeks back but that was more of a laugh. This is the real deal. She told me she wanted to get married again. I feel so happy."
The wedding plans are currently on hold as under the terms of his prison release, Blake - who was jailed for attempting to pervert the course of justice and grievous bodily harm - is unable to return to London until February and is currently receiving treatment at a rehabilitation clinic in England.
Until his return, Blake has pledged to stay faithful to Amy, despite admitting to sleeping with other women in recent months.
He said: "I'm not going to go near anyone else. I've discussed it with Amy. She understood we both had to try and move on. But I think deep down she always knew we'd tie the knot again."
Blake divorced Amy in July on the grounds of her infidelity. They first married in May 2007.
