Pregnant Kim Kardashian has dead skin bitten off by fish on purpose: Watch video
But apparently, she's not a fan.
Doctor fish (also known as Garra rufa) are used in pedicures to eat the dead skin off of a person's feet. The fish are kept hungry, so that they forage for food in a person's epidermis. The practice is illegal in some U.S. states and in most of Canada, because since the fish are used on multiple patrons, it's deemed unsanitary.
Kim's sister, Khloe, videotaped Kim and Kourtney getting the fish pedicure. While Kourtney was calm, Kim fully freaked out -- even breaking down into tears.
