The 27-year-old British singer first hooked up with filmmaker Reg Travis after splitting with Blake Fielder-Civil last year.
And he said that despite her past problems, Amy has moved on from her dark days.
He told The Sun, 'We've been together nearly a year now and we're very happy. Amy's doing well, she's fine. She's healthy and happy.
'She's still writing and recording stuff for her new album. She's really throwing herself into it.'
He added that Amy is 'very excited' about her new material, which fans have had a five-year wait for.
