The singer revealed that she has been "tinkering away" on new music in the studio with long-time collaborator Greg Kurstin.
"I'm not going to put anything out until I've got an end product which I think's amazing - or, you know, good," Allen told NME.
"I don't think there's going to be anything out in the next few months, but hopefully in the next year."
The star added that the new material will "definitely" deal with her life and experiences as a parent.
Allen - who will go by her married name of Lily Rose Cooper - recently teamed up with Pink on a new track called 'True Love'.
