What happens when you mix two hot young artists, a rockin’ backyard and adult-size animal onesies? Miley Cyrus’ awesome new music collaboration with Ariana Grande, of course.

Performing a rendition of the Crowded House rock classic “Don’t Dream It’s Over” – while decked out in cozy unicorn and mouse onesies – Cyrus, 22, and Grande, 21, recorded the music video in the Bangerz singer’s own backyard.

The duet, released to PEOPLE and Entertainment Weekly, is all in the name of raising awareness for The Happy Hippie Foundation, a nonprofit organization Cyrus recently launched to shed light on issues surrounding homeless youth and other vulnerable populations, including the LGBT youth community.

“No one should have to hide who they really are, no matter what his or her name, gender, status or orientation,” the singer said recently. One of the foundation’s missions, added Cyrus, who has been an outspoken advocate for LGBT rights for years, is “to make sure those who question the value of themselves and their lives feel protected and loved.”

Teaming with Facebook, Cyrus kicked off the initiative on May 5 with Backyard Sessions, a curated collection of music video collaborations between Cyrus and other like-minded artists, including Grande, Joan Jett and transgender punk rocker Laura Jane Grace.

Her first session was a collaboration with Jett for a rendition of “Different,” a track off Blackhearts’ 2013 album Unvarnished. “I think what Miley’s doing is wonderful and important to help people find their authentic selves,” Jett told Rolling Stone of the foundation.
