WATCH: Brie Larson is Actually the Fourth HAIM Sister

Meet Brie Larson: Oscar-winning actress and newest member of HAIM.

In a different kind of role for the Room star, Larson plays Frime Haim, the fourth and lesser-known Haim sister who cannot shake the music bug. Seriously. She’s very much into the idea of making HAIM a quartet, but the three original band members are hesitant of their identity thefting, Kool-Aid drinking sister. Just … watch.

Larson isn’t the first HAIM wannabe, though. Remember when Melissa McCarthy and Aidy Bryant teased this SNL episode and Bryant insisted she was a part of the band? Yeah, we do too.
