Billie Eilish and FINNEAS just won Song Of The Year for their hit "bad guy" at the 62nd GRAMMY Awards. Eillish and her producer/big brother accepted the award together on stage.

Earlier in the show, the 18-year-old pop powerhouse performed "when the party's over" for her GRAMMY stage musical debut. She also won Best Pop Vocal Album, for her massive 2019 debut LP, When We All Fall Asleep, Where Do We Go?, which "bad guy" is on. FINNEAS earned Producer Of The Year, Non-Classical as well, for his work on the album.
