SPIN‘s 2014 Artist of the Year Sia stopped by The Late Late Show With James Corden wearing her signature giant bow and wig to sing with the comedian on his massively popular “Carpool Karaoke” segment. She also bantered about her sense of direction, her anonymous visage, and, uh, aliens. They also sing her biggest hits: “Chandelier,” “Elastic Heart,” “Diamonds,” “Alive,” (from this year’s This Is Acting) and “Titanium,” all of which you can watch below.
