Chrishell Stause is her partner G Flip's biggest fan!

On Tuesday, the Australian musician — who identifies as non-binary and uses they/them pronouns — performed a snippet of their new song, "Waste of Space," on Instagram.

"I wrote this song about being non binary," G Flip, 27, wrote over the clip.

"I grew up uncomfortable, 11 years old and I wanted to die," they sang. "I don't feel like I'm a girl nor a boy, so where do I lie? Have you ever felt... have you ever felt like a waste of space? That's what they say, I'm a waste of space inside my brain."

The Selling Sunset star, 40, showed her support for her partner's new music in the comments section, writing: "So so so so beautiful♥️ a voice to change the world."

Stause's Selling Sunset costar Emma Hernan also shared, "​​Your talent is out of this world 🌎.. Also you are the best space in ever[y] room I've been in with you!!!❤️❤️."

Last week, the Dancing with the Stars alum opened up about her romance with G Flip in an interview with Vogue, describing their relationship as "unlocked."

"It's when they have the key to your heart, but the walls are down and there are no rules or regulations, just love and support," Stause explained. "Plus, it ties into real estate, which is actually quite cute!"

Stause revealed that her "favorite part" of their relationship "is just being around G."

"It's such a mood-lifting experience; if you ever had the pleasure of being in the same room with them, you would quickly see what I mean," the reality star added. "I love feeling that endless support of just wanting the other person to be fully who they are."

Though Stause mentioned that she and G Flip "want some different things" — the All My Children alum has spoken openly about wanting kids, while she says "that's not where" the Australian singer is in their life right now — the pair's relationship is something Stause will always cherish.

"It really is just a super-open, communicative situation where we don't want to block anything for either person, and we want to offer each other love and support no matter what form it takes," she said. "Without a doubt, we'll always be in each other's lives, so that feels good. I wouldn't have known that I'm open to so many things without them kind of opening my eyes."

Stause and G Flip first went public with their romance during the Selling Sunset season 5 reunion after moderator Tan France asked if she was seeing anyone special five months after splitting with costar and boss Jason Oppenheim.

On the PEOPLE Every Day podcast in May, G Flip shared how they were introduced to Stause.

"We met last year at Halloween. We were both with our ex-partners then ... And then, we obviously separated from our partners, and we just started talking and stuff," G Flip told host Janine Rubenstein. "We just found a lot of similarities, even though people would think we are from, like, different corners of the world. We find ourselves so similar sometimes."
