The troubled singer - who completed a short stint in rehab for problems with alcohol last week - is hard at work on the follow up to 2006 album 'Back to Black', and although her boyfriend Reg Traviss says she's being creative, he doesn't know when her new material will be ready.
The film director told The Sun newspaper: "I don't really ask how long it will be because I know with an artist, you don't ask 'How long do you think?'
"If you say to a scriptwriter 'How long until it's finished' it puts too much pressure and I presume it's the same with song-writing.
"Better not to ask what the timeframes are. She's working all the time."
Amy checked into The Priory clinic in London after her father raised concern over the amount she was drinking, ahead of her making a string of festival appearances this summer.
Her stay only lasted a few days, but she is reportedly still to be seen as an outpatient.
The 'Tears Dry on Their Own' singer's spokesperson said: "She is now looking forward to playing shows around Europe this summer and is raring to go.
"She would like to send a huge thanks to all her fans for the messages of support she has received over the last week and can't wait to see them."
Amy's first concert appearance this summer will be at Kalemegdan Park in Serbia on June 18.
