“Not a drill, not a joke…” Pop star Kesha has sparked widespread disbelief after publicly begging fans to mail her their real human teeth, revealing her bizarre obsession with turning fan teeth into crowns, belts, and home decor.

Kesha’s incoming fan mail may include letters, photos and apparently teeth, at least she hopes.

The 39-year-old “Die Young” singer asked fans to mail her their pearly whites in a July 29 X post, writing, “ICYMI: I want your teeth.” She also provided a forwarding address in Los Angeles.

The singer songwriter’s fascination with dentition predates the odd request. She revealed in a July 15 appearance on the podcast “Las Culturistas with Matt Rogers and Bowen Yang” that she collects teeth.

“Well, the teeth started when I became obsessed with my fans,” Kesha said. “And then someone was like, ‘My child lost their teeth.’ And I was like, ‘Can I have them?’ Cuz I want to make jewelry out of it.”

“And so, then I made a necklace and an earring and then a belt and then a crown. Oh, the crown’s wild. And then I just started collecting them cuz it kind of freaks out straight men,” Kesha continued, adding she stores the teeth in little jars that are scattered all over her home.

Kesha is serious about adding more teeth to her collection and will ask anyone for a donation, including the “Las Culturistas” crew, whom she told, “Give them to me.”

“Can I have your teeth, please? Can I actually have them?” Kesha said. “And it’s not a drill. And it’s not a joke. I’m a pop star, and I need your teeth.”

As the “Praying” singer made her plea to members of the “Las Culturistas” podcast, they revealed that they know exactly where their teeth are.

“If everyone brings in their teeth… She’s a pop star, and she needs your teeth. That’s a rule of culture. Number eight,” Rogers joked. “She’s a pop star, and she needs your teeth. If y’all want to bring in your teeth, we can put them in an envelope or something and send them off. Y’all bring your own stamps.”

He added: “Cuz I ain’t going to get stamps.”

Kesha previously opened up about her love of teeth on “Call Her Daddy,” telling podcast host Alex Cooper that she’s like the tooth fairy.

“It’s like the teeth, it just reminds me, (that) I have a little piece of the people I love,” she said.
