This is just nasty!!! Ke$ha asked fans to send her teeth and she got over 1,000. But wait it gets better worse, SHE IS WEARING THEM... ON HER BODY... VOLUNTARILY. Gross. 

She said, "I asked for them to send me their teeth and I got, like, over 1,000 human teeth...I made it into a bra top, and a headdress, and earrings, and necklaces. I've worn it out!"

She made a whole outfit!!!

And yes, that is a picture of her tooth crown.
