Upon launching her Happy Hippie Foundation in support of homeless and LGBT youth, RCA's Miley Cyrus has begun rolling out collaboration videos with an array of stars from all genres.

The videos, released as segments of the charity's "Backyard Sessions," have so far featured appearances from Joan Jett, Melanie Safka, Rise Against's Laura Jane Grace and Atom and, most recently, Republic songstress Ariana Grande.

The latter joined Cyrus for a cover of Crowded House's 1986 hit "Don't Dream It's Over." Boosting the Bangerz star's message of equality for all, they proved that even a unicorn and a mouse/bear can make beautiful music together. Their rendition (seen below) is both breathtaking and whimsical. 

We've already bought a box of matching unicorn onesies to don around the office whilst singing a collection '80s hits.
