The 'Rehab' singer – who started dating the film director around May this year, just weeks after ending her on/off romance with ex-husband Blake Fielder-Civil – has reportedly pledged her love to Reg by asking him to move into her London home.
A source told the Daily Mirror newspaper: "She's asked Reg to move in with her and he's agreed. He has met all the family and is a hit."
Friends close to the 26-year-old songstress have credited her new lover's "calming influence" as the reason why she is re-focused on her new album, which is now expected to go on sale in January 2010.
The source explained: "It's been an incredible past few weeks for Amy. She has completely turned her life around. It has been a long time coming – and she's been writing songs for what seems an eternity – but finally Amy is satisfied and believes she has an album worthy of a four-year wait."
Amy's last album was 2006's phenomenally successful 'Back to Black', but her follow-up has been delayed time and again because of her problems with drink and drugs and her divorce from Blake.
But the star has now learnt to use her past problems as inspiration.
The source added: "She's held meetings with the record label, Universal, and they are putting everything into promotion. A lot of the material covers her romance with Blake Fielder-Civil and their acrimonious split, plus, or course, her battle with the booze and drugs.
"It is very raw and very personal – it promises to be another classic. She is now narrowing down the material and hopes it'll be on shelves by the New Year."
