Kesha has joked that she keeps human teeth in her home to scare off "straight men".
During an appearance on the Las Culturistas podcast on Wednesday, the Tik Tok hitmaker told co-hosts Bowen Yang and Matt Rogers that she has been collecting teeth for years.
"Do you know I collect teeth? I do," she said. "Send them over. The teeth started when I became obsessed with my fans, and then, someone was like, 'My child lost their teeth,' and I was like, 'Can I have them?'"
Kesha went on to note that she uses the teeth to make jewellery and accessories.
"I made a necklace, an earring and then a belt and then a crown," the 39-year-old recalled, before joking: "Then I just started collecting them because it kind of freaks out straight men."
The Your Love Is My Drug star revealed that she also displays the teeth in her home.
"I just started putting (the teeth) all over my home... In little jars," she smiled.
And while Bowen and Matt noted that the collection may be controversial, Kesha argued that when people lose human teeth, they probably just throw them out anyway.
"Do you flush them down the toilet?" the Die Young singer asked. "Where are they going? Give them to me... Can I actually have your teeth, please? It's not a drill, not a joke. I am a pop star and I need your teeth."
In an interview for the Call Her Daddy podcast in May, Kesha shared that she also has a collection of cat teeth.
"It just reminds me when I have a little piece of the people I love," she explained. "I've been collecting them for a while now... My cats had to get their little teeth taken out, their little kitty wisdom teeth. I collect those too. I'm like the tooth fairy."
