Her Go-To Karaoke Song Is "We Didn't Start the Fire" by Billy Joel
Greta Gerwig blames her love for the song on being "one of those teenage girls who think knowing all the words to this song will guarantee you a boyfriend until you realise about 30 seconds too late that it won't." She may have the boyfriend part locked down now, but I think we all would still be interested in hearing Greta sing karaoke to Billy Joel.
