Miley Cyrus has shared a third collaboration with Against Me!’s Laura Jane Grace in support of the Bangerz singer’s Happy Hippie Foundation. This time, the pair -- along with Grace’s bandmate Atom Willard -- delivered a performance of Against Me!’s own “True Trans Soul Rebel,” a track from the band’s 2014 full-length, Transgender Dysphoria Blues -- the quartet's first album since Grace announced her transition as a transgender woman. Watch their moving rendition in the video above.

Their “True Trans Soul Rebel” performance is one in a series of collabs for Cyrus’ ongoing Backyard Sessions. Previously, Cyrus and Grace joined Joan Jett for a cover of “Androgynous,” a song from the Replacements’ great 1984 album, Let It Be. Cyrus and Jett also served up a performance of Jett and the Blackhearts' Unvarnished track, "Different."

Cyrus recently launched her Happy Hippie Foundation, which provides support to LGBT and homeless youth. She told the Associated Press she hopes to use her celebrity platform to help her new organization thrive.

“When you have all eyes on you, what are you saying? And that’s what I asked myself a lot,” Cyrus said. “It’s like, I know you’re going to look at me more if my [breasts] are out, so look at me. And then I’m going to tell you about my foundation for an hour and totally hustle you.”

The Backyard Sessions aren’t the only collaborations Miley has up her sleeve. She's reportedly working on an album with her friend Flaming Lips frontman Wayne Coyne. Coyne opened up about their time in the studio together, saying the “Wrecking Ball” singer “does the pop thing so great, so it still feels pop, but a slightly wiser, sadder, more true version,” adding that their work reminded him of of Pink Floyd and Portishead.
