Grimes Helps Stella McCartney Promote New Perfume

"Sustainability in fashion stuff is something I really care about," Grimes explains at the beginning of her new advertisement for Stella McCartney’s perfume. "That's one of the reasons I like Stella so much," the singer/songwriter/producer continues. "Not something that exists for the sake of aesthetics, but something that exists because someone cares about it."

On Instagram, McCartney wrote, "So proud to share the same values as @actuallyGrimes." Watch the ad above.
