She's apparently making an "album film."
It is believed to be the code name for the next installment versus the actual album's working title. A Beyoncé Twitter fan account, who's offered other reliable information in the past ahead of time, claims the album film will be in collaboration with Kahlil Joseph, an Indian-born American film, TV and stage actor.
At first we interpreted "album film" as a visual album, but something tells us Beyonce wants to top her last release and make a legit movie.
As Idolator points out, Beyonce has clued fans in here and there on Project Lemonade.
She's also rumored to be releasing an album with Jay Z exclusive to TIDAL later this year.
