sia in beyonce's beysment

sia wrote in an article about how she helped beyonce in writing songs for her new album, and she kinda said something like beyonce used to come and check up on her in the room where she was writing songs and help her with it. but the netizens made a meme out of this statement saying beyonce locked sia in her basement. it started with brazilian twitter community but then it rose to fame and stan twitter made it more popular. thats it. i cant believe i have an exam tomorrow and im writing this. anyways glad to help lol.
