Billie Eilish designs, reveals new vegan and sustainable Nike Air Jordans

Each sneaker is 100% vegan and one pair is bright green.

Billie Eilish is putting her stamp on one of Nike's upcoming Air Jordan shoes launches.

The singer has teamed up with Nike to design two exclusive pairs of Air Jordans that are 100% vegan and made from more than 20% recycled material.

One pair is a tan-colored Air Jordan 15, representing her new "Happier Than Ever" era, while the other is a lime-green Air Jordan 1 KO. The latter is an homage to her former signature hair color.

"I am SO excited to finally share my two air jordan silhouettes with you," Eilish captioned a duo of photos on social media of herself wearing the sneakers.

She continued: "I've always loved @jumpman23 and it was such an incredible and surreal experience getting to create these, especially in a sustainable fashion.

The "Lovely" singer opened up behind-the-scenes with Nike in a series of videos to share how her sustainable new shoes came to be.

“This color is such a classic, stupid, little 'old me' thing, I guess," she told Nike. "I really wanted to kind of have almost like an ode to myself … this was me, for a while."

"They're gender-neutral, which I really love," she added. "You can be whoever and whatever you want with these."

Both shoes launch on Sept. 27 on store.billieeilish.com and on Sept. 30 on the Nike SNKRS app.

The news surrounding Eilish's new sustainable Nike Air Jordan sneaker drop come shortly after she collaborated with Oscar de la Renta for her recent Met Gala appearance.

She wore a glamourous vintage Hollywood-inspired dress by the designer and shared that moving forward, the label will be completely fur-free.

"I am beyond thrilled that @fernandogarciam1205 and @tokibunbun and the entire team heard me on this issue, and have now made a change that makes an impact for the greater good, not only for animals but also for our planet and environment too," Eilish said in a post about her work with Oscar de la Renta. "I'm honored to have been a catalyst and to have been heard on this matter. I urge all designers to do the same."
