A newly-blonde Billie Eilish just dropped a new track,  “Lost Cause” about an old boyfriend.

The song is off her upcoming album, “Happier Than Ever,” which is expected out at the end of July.
The video is a take on a sexy slumber party and apparently, was tons of fun to shoot.
“We had the time of our lives being hot & shooting this heeheeeeeehee,” the singer wrote on Instagram,

Good for her!
