One Direction's carpool karaoke session on The Late Late Show with James Corden was so eagerly anticipated by fans, #1DCarpoolKaraoke was trending on Twitter hours prior to the show's airing on Tuesday night (Dec. 15). Well, Directioners finally had the time come, and the karaoke clip is so epic, it's hard to imagine anyone's expectations not being met.

The guys spend a beautiful afternoon driving around Los Angeles and belting out 1D hits like "Best Song Ever," "Story of my Life," "Perfect" and "What Makes You Beautiful," among other songs, and part of the fun of the session is the hilarious asides made when the members aren't singing. Louis discusses a milk-wielding super-fan; Niall is forced to play "sleep, marry, cruise" with new beau Selena Gomez as one of the options.

Oh, and at one point they all don jean jackets and performed choreography to "No Control." That sound you just heard is a million Directioner hearts exploding.

As most pop fans know, 1D is promoting Made in the A.M. before setting forth on a hiatus next year. Click to watch recent Carpool Karaoke sessions with Justin Bieber and Carrie Underwood.
