Billie has a book full of all of her songs even the ones not yet released and the ones that didnt come out! She has all her ideas and basically everything about her inside, it's literally the story of her life. She'd probably never put it on display as it's to private and personal and it's way to valuable to her. She also has drawings all over her wall that she covers so nobody can see them. She has words on there too and only about 5 people has been allowed to see her wall! Anytime she's getting interviewed in her room she covers her wall with blankets!!!
