Watch: Billie Eilish's Tiny Desk (Home) session.

Billie Eilish is the latest artist to perform for NPR's Tiny Desk Concert, with a twist - actually performing with a cardboard cut-out replica of the iconic office set-up.

During the performance she revealed: "So, obviously, we are not actually at 'Tiny Desk' because this is a cardboard cutout of it, but it's still real. It's just not in-person real. I'm honoured to be here."

Eilish and her brother Finneas performed two songs, 'My Future' and 'Everything I Wanted'.
