Billie Eilish has unveiled a delightful acoustic performance of her song “Billie Bossa Nova” on Monday (December 20). The visual was directed by Philip Andelman for Gucci.

In the clip, Billie is joined by FINNEAS as she runs through the bossa nova-infused cut. The track serves as a genre curveball on Eilish’s sophomore album, Happier Than Ever, which also contains singles “My Future,” “Therefore I Am,” “Your Power,” “Lost Cause,” “NDA,” “Happier Than Ever,” and “Male Fantasy.”

Earlier this month, Eilish joined the club of Saturday Night Live hosts to also double as the night’s musical act on their own episode. The singer appeared on the late-night show on December 11 to make her hosting debut and topped the night off with performances of “Happier Than Ever” and “Male Fantasy.”

Over 47 seasons, Saturday Night Live has only ever had 35 musicians appear as both host and musical guest in the same episode. Eilish joins the likes of Harry Styles, Nick Jonas, Paul Simon, Dolly Parton, Britney Spears, and more.

Eilish’s parents introduced her for the first song of the night, a barrelling performance of “Happier Than Ever.” The stage recreated the airy living space of the track’s music video, first shared alongside the release of the singer’s sophomore album Happier Than Ever. Over the course of the performance, the props and furniture are stripped away until Eilish has a full area of empty space to dump out the intense emotion of the song.

Later in the night, Eilish stripped back even more with a captivating performance of “Male Fantasy,” once again recreating the vision of the song’s music video. She appears under a spotlight in a set resembling a darkened room, with just a small tree and a rug making up the room’s decor and only two windows as additional sources of light. Eilish situated herself on the floor with her brother and collaborator Finneas for “Male Fantasy,” soaking in the stellar vocal performance accompanied only by an acoustic guitar.
