Billie Eilish linked up with James Corden for an edition of Carpool Karaoke.

The pair sang along to Eilish's tracks "Ocean Eyes," "bad guy," "all the good girls go to hell," and "when the party's over." Eilish, who talked about meeting Justin Bieber for the first time at Coachella, even played the ukulele. "He just stood like five feet away from me and perfectly still. He had the face mask, so all I could see were his eyes. But they were his eyes," the singer recalled.
