Warning: there will be spiders.

Billie Eilish has joined James Corden for a Christmas special of Carpool Karaoke, and yes, it is just as iconic as you'd expect. While cruising around the block, Billie and James bash out some of the artists' most iconic tunes including 'bay guy,' 'Ocean Eyes,' and a cover of The Beatles' 'I Will' on ukulele. They also chat a bit about Billie's parents, how she met Justin Bieber, and eventually rerecorded her number one hit featuring his dulcet tones. The pair also visit Billie's parents' home, where she forces James to hold her pet spider. He is, understandably, not all that impressed. Billie's episode of Carpool Karaoke was part of Corden's Christmas special of The Late Late Show (not the Irish one, let it be known). The episode featured a festive lineup including the incredible and iconic Mariah Carey singing her banger of a hit 'All I Want For Christmas Is You' to mark the song's 25 year anniversary. It also finally reached number one in the US Billboard chart. Class. Billie's Carpool Karaoke comes after she successfully bagged the top spot of Spotify's most streamed new release of 2019. WHEN WE ALL FALL ALSEEP, WHERE DO WE GO? was the platform's most popular release of the past year, surpassing Ariana Grande's thank u, next and Taylor Swift's Lover.  Billie also nabbed the spot for second most streamed song with 'bad guy', as well as the second most streamed artist of the year over all. Not bad. You can check out the Billie Eilish's Carpool Karaoke in full here: https://www.youtube.com/watch?v=uh2qGWfmESk&feature=emb_title
