i am so here for this! i haven't put together a damned thing for him yet aside from his career of choice, so it's wide open in terms of who he's worked for and when, but i'd love it if they're currently working together. maybe he's been in the studio in the past where he's put his (an-asked for) two cents in on a track and she's kept him in mind for future projects and tapped him for this new album?
