Miley Cyrus and Ariana Grande have teamed up to cover Crowded House's "Don't Dream It's Over,
for Miley's Backyard Sessions.
The two were decked out in a unicorn and mouse onesie, and performed the classic song in Miley's backyard while sitting on a green inflatable couch.
The performance will raise awareness for Miley's Happy Hippie Foundation, which is her non-profit organization that battles the injustices faced by the homeless and LGBT youth.
