“happy Halloween virgins  ,” he captioned an Instagram carousel of pH๏τos and, of course, the eyebrow-raising video.

Naturally, followers were horrified that the “Bloody Valentine” singer, 32, would glorify drugs in any capacity given his fan base consists of a lot of teenagers.

“Ok but this? Hell na, might ur music be good but the drugs? not that much,” wrote one fan.

“I cannot keep defending y’all wtf is this ,” commented another.

“Not cool with the snorting and having teens idol you,” wrote a third follower.

“Him thinking it’s ok to post a video doing a f–king line is crossing a f–king line after every artist we’ve had over dose in the past few years,” commented another.

“Okay, Ik there r gonna be ppl saying they didnt ask but this is not okay. Even if it’s fake, and a joke,” noted one more. “This is not okay to promote to your fans and it’s even worse for the children they both have. Highly disappointed, really not a fan of you anymore at this point. This is f–ked.”

Other followers criticized the “Transformers” actress, 36, for being a mom and participating in public posts involving “drugs.” (Kelly is also a parent.)

“You’re a mother ? Oh how proud your kids will be years from now when they see this,” commented one person.

“Knowing she has kids that’ll grow up and see this is so sad,” wrote another.

The backlash didn’t seem to prevent Kelly and Fox, who got engaged in January, from continuing their controversial Halloweekend, as they further fueled fire when they followed up their drug-addled costume with one in which he dressed as a priest and she dressed as a Sєxualized worshipper on a leash.
