Billie Eilish in 'Lost Cause' video

As Billie Eilish continues to tease her upcoming album Happier Than Ever, she released a new song called "Lost Cause" on Wednesday.

The track arrived with a self-directed video which sees Eilish surrounded by a group of women in what appears to be a sleepover in a mansion by the beach. There's silly string, dancing and lots of junk food.

The new song comes ahead of the full album, which is out July 30 via Darkroom/Interscope Records.

Watch the video below.
