Warren does not usually allow anyone into her Hollywood Hills office, which she describes as a "cluttered, airless room". In 2012, Warren stated that nothing in her office had been cleaned or moved for 17 years because she is superstitious; she prefers to think of that room as her "secret world". In that room, Warren records melodies with a tape recorder on which she plays them again and chooses the songs she likes the most. Warren did allow part of a 2016 interview with "CBS News Sunday Morning" correspondent Ben Tracy to be taped in the office.
