WATCH: Billie Eilish shares video for brand new single 'Therefore I Am'

Following the release of 'My Future' in July, Billie Eilish is back with a new single 'Therefore I Am' – as well as an accompanying video, which finds the American pop star running riot in an abandoned shopping centre.

News of the track, which was co-written and produced by Billie's brother and frequent collaborator Finneas, was first teased just days ago.

Billie is set to give 'Therefore I Am' a live airing at the 2020 American Music Awards on November 22.
