The fact that she has her own Carpool Karaoke says a lot about the huge year that Billie Eilish has had.
It also speaks to the quality of her debut album 'When We All Fall Asleep, Where Do We Go?' - that with just one album (and a few pre-album singles) under her belt, she has enough belters for James Corden to caterwaul along to.
Of course, 'Bad Guy' features as well as 'All the Good Girls Go to Hell' and 'Ocean Eyes'.
Billie Eilish - who just turned 18 this week - also speaks about the artists who she has been starstruck by this year (including Justin Bieber) and they visit her parents' house, where Corden meets her pet spider.
And there's even a Beatles cover.
