Kris Humphries

Kim Kardashian filed for divorce from Humphries after only 72 days of marriage. His demand for an annulment kept the couple married until May 2013 when he finally agreed to a divorce. Us Weekly Magazine reports that Christie's will auction on October 15, 2013 the $2 million, 20-carat Lorraine Schwartz diamond engagement ring Humphries gave Kardashian. It is expected to sell for between $300,000 - $500,000.
