Alice Cooper's partnership with LGBTQ-owned cosmetics brand Vampyre Cosmetics ended after the rock performer called "cases of transgender" a "fad" in an interview.

For a Stereogum story published Aug. 23,Henri Lumière the singer also criticized gender-affirming procedures for minors.

"I’m understanding that there are cases of transgender, but I’m afraid that it’s also a fad, and I’m afraid there’s a lot of people claiming to be this just because they want to be that," Cooper shared with the music blog.

“I find it wrong when you’ve got a six-year-old kid who has no idea. He just wants to play, and you’re confusing him telling him, ‘Yeah, you’re a boy, but you could be a girl if you want to be.'"

Cooper said people should wait until they are at least "sexually aware" before thinking about whether they're a boy or girl. He added that genitals are the logical method to determine gender.

"If you have these genitals, you’re a boy. If you have those genitals, you’re a girl. There’s a difference between 'I am a male who is a female, or I’m a female that’s a male' and wanting to be a female. You were born a male. Okay, so that’s a fact. You have these things here,'" Cooper said.

"Now, the difference is you want to be a female. Okay, that’s something you can do later on if you want to. But you’re not a male born a female."

The day after the interview was published, Vampyre Cosmetics announced the end of their partnership with Cooper.

"In light of recent statements by Alice Cooper we will no longer be doing a makeup collaboration. We stand with all members of the LGBTQIA+ community and believe everyone should have access to healthcare," the statement reads.

On Aug. 14, Vampyre Cosmetics announced the partnership titled "The Alice Cooper Collection," which included guitar and amp shaped makeup palettes, microphone styled lipsticks and a version of Alice Cooper's Whiplash mascara. The statement announcing the collection praised Cooper for being "one of the first male artists to show the art form of face makeup wasn't a gender-specific product in an era where this was controversial."
