Billie Eilish joined James Cordon in the passenger seat for a special Christmas episode of Carpool Karaoke.
While cruising around, the pair belted out her hit singles 'bay guy,' 'Ocean Eyes,' and a very impressive cover version of The Beatles' 'I Will' on ukulele.
In between the hits, the pair discussed everything from Billie's parents to meeting Justin Bieber.
They also paid a visit to Billie's home house where she forced James Cordon yo hold her pet spider.
Because, of course, Billie Eilish has a pet spider. Duh..
It's been a busy few weeks for Billie as her track WHEN WE ALL FALL ALSEEP, WHERE DO WE GO? claimed the top spot as Spotify's most streamed release of 2019.
Meanwhile, James Cordon is due back on our screens on Christmas Day as he reprises his role as Smithy in Gavin and Stacey for a one-hour Christmas special.
