Word is a member from PopJustice (a reliable one who revealed she was working again with Mirwais two years ago and also that she was recording a part for a Dua Lipa remix) said that the work for her next album has already begun and that she is working with Pat Leonard. He then removed his post (apparently another reliable member asked a moderator to delete it because whatever M has in store right now musically is supposed to kept secret).
