Part of the price of being a celebrity is that you are going to likely attract some crazy fans. And some of those crazy fans are going to send you some weird things in the mail.
Ke$ha once received a tooth from a fan in 2011. Only instead of being creeped out, she had a brilliant idea. She asked her other fans to send her teeth too and they did, bringing the total to over 1,000 fan teeth, which she made into necklaces, earrings, a bra top, and a headdress.
