Apple Music’s upcoming Carpool Karaoke standalone series will consist of 16 half-hour episodes, Variety reports. The show, a spinoff of the popular segment on The Late Late Show with James Corden, will feature different hosts for each episode. Carpool Karaoke will also be “more of an interview series” — it’s unclear how much time will be spent talking, and how much time will be spent singing. A few of the host/guest combos have already been announced. While the show will feature pairings such as John Legend with Alicia Keys and Seth MacFarlane with Ariana Grande, other groupings might be more unexpected: Billy Eichner with Metallica and Michael Strahan with Jeff Gordon, for instance. No release date has been set yet for the show.
