Lily Allen has recently stated in an interview that she's hoping to release her fourth studio album, which apparently will be called "The Fourth Wall", in June 2017.
She has already released several snippets of new songs on her Instagram and Snapchat account and she also said that a couple of songs on her new album will be about the state of the world, the relationship between her and her children, substance abuse, her marriage breakdown and other topics. According to her, there will be two politically-centered songs on "The Fourth Wall".
She has been working on the new album with several people, including Fryars, Lil' Silva, Sean Paul and Nicky B. Moreover, she has probably teamed up again with Greg Kurstin and Mark Ronson (this is not confirmed, though).Sources:http://www.josepvinaixa.com/blog/lily-allens-fourth-studio-album/https://muzwave.com/2016/04/lily-allen-fourth-album-fourth-wall/https://audioboom.com/posts/5677003-ep-6-lily-allen?utm_campaign=detailpage&utm_content=card&utm_medium=social&utm_source=twitter
EDIT: Just a brief information for the ones who visit this thread for the first time now: The confirmed album title is "No Shame" and not "The Fourth Wall". The initial rumours about the album coming out in June 2017 were false as well - it has recently been confirmed that the official release date is the 8th of June 2018.
