The Smile hitmaker releases her third album, Sheezus, on Friday after taking four years out of the music industry to start a family.
Last month she addressed criticisms of the early singles from the record, describing them as "beige", but told fans the best songs were yet to come.
However, now Allen has admitted Sheezus is not her greatest work but insists she is just happy it "slightly resembled" her signature sound after so long away from a recording studio.
She tells Q magazine: "I felt such relief that I could connect with myself again.
"I don't want to slag off my own work because I am proud of this record, but I think there's probably better to come from me and there's been better stuff in the past as well.
"I was just relieved to have something that slightly resembled me because I'd felt so far away from me."
