Yesterday The Late Late Show With James Corden had a little twist when Alicia Keys stepped into Corden’s shoes to host the Tuesday show.

Then, the new host brought out Billie Eilish to perform her song “Ocean Eyes” together, in an intimate acoustic setting that left everybody in the studio audience speechless.

After the performance, Eilish surprised Keys with a short clip of her own cover of one of Alicias’s biggest hits, “Fallin’”, in which a 12-year-old Eilish can be seen singing and playing the song on the piano at a school talent show.
