Miley Cyrus and Ariana Grande are singing to support homeless LGBT youth in a unicorn and mouse-bear onesie. The popstars covered the '80s classic by Crowded House "Don't Dream It's Over" and it's soooo cute. In the video, they perform on top of a blow-up green couch, and at one point Cyrus calls Grande "the cutest mouse-bear I've ever seen," and Grande calls her "the cutest unicorn in the world." 

The duo recorded this song as part of a series of backyard sessions Cyrus hosts to celebrate the launch of the Happy Hippie Foundation, an organization that advocates for LGBT homeless youth. Previously, she invited Laura Jane Grace of Against Me! and Joan Jett to join her.
