Billie Eilish: "Nobody that knows me thinks I'm a dark person"

The multiple Grammy-nominee with the #1 hit "Bad Guy" says she is coming out of the "joyless" and "torturous" feeling that clinical depression and unwanted fame brought her. In this intimate conversation with "CBS This Morning" co-host Gayle King, Eilish and her brother, Finneas O'Connell, discuss the creative spirit behind her debut album, "When We All Fall Asleep, Where Do We Go?" (Originally broadcast on "CBS Sunday Morning" on December 8, 2019.)
