While James Corden takes a break from hosting The Late Late Show there’s an all star cast of celebrities filling in, and last night it was the turn of Alicia Keys. The “Fallin’” singer welcomed pop sensation Billie Eilish to the couch as her guest, and what followed was pure magic.

“I didn’t bring this thing here for nothing,” Keys coyly smirked as she flipped open her desk to reveal a piano. After asking for the lights to be dimmed, she started playing a beautiful piano rendition of “Ocean Eyes” from Eilish’s 2017 mini album don’t smile at me. 

Keys began the duet with her soulful intonations, and as she traded off lines with Eilish the two seemed to be completely in sway with one another. Eilish and Keys have been mutually stanning each other for a while now – when accepting an award at the 2019 iHeartRadio Music Awards, Keys shouted her out: “I want to thank all the artists out here who continue to break the mold, who continue to inspire me. Some of them like Post Malone, SZA, and Rosalia. And so many others that are in the audience like Taylor (Swift), Maren (Morris), and Billie Eilish who’s in the building too, who I just love.”

While a lot of the music industry seems to be winding down for the festive season, Eilish has been nothing but busy. Last week she released the self-directed video for “xanny” and reportedly sold her behind-the-scenes documentary to Apple TV+ for a cool $25 million.
