Billie Eilish Has Epic Sleepover In 'Lost Cause' Music Video

We can't get enough of our girl Billie Eilish. The 19-year-old dropped another new song from her highly anticipated sophomore album Happier Than Ever, "Lost Cause," along with an accompanying music video.

In the track, Billie calls out her ex for his lame, ex-worthy behavior while having a blast of a sleepover with her GFs in the video.
