On Monday (December 9) Alicia Keys took over hosting duties on The Late, Late Show With James Corden, and surprised the all-female audience by performing a duet of "Ocean Eyes" with her guest, Billie Eilish.

The R&B star opened her talk show desk to reveal a piano inside, and the two delicately exchanged lines of the emotional song before coming together at the end for some bone-chilling harmonies. The pop titans embraced in a warm hug after they were done singing, and we're not crying you're crying.

During the same segment, Keys mentioned that she covered "Ocean Eyes" on Instagram and asked if Eilish ever saw it. The 17-year-old, of course, did and explained how it blew her mind. She then surprised the guest host by revealing that she covered "Fallin'" at a talent show in 2014, and shared a clip of the performance (that she totally nails). For anyone who doesn't want to do the math — Eilish was 12 years old in 2014. Pretty crazy.

The women will likely reconnect at the Grammys, where Eilish is nominated for a whopping six awards (and broke a record in the process) and Keys is hosting for the second year in a row.
