Oprah Winfrey has defended the Kardashian's against harsh critics saying they are a hard working family who should be respected for their success. The 61-year-old media proprietor said that they are really hard-working people and recalled how she interviewed them on "The Oprah Winfrey Show", reported Ace Showbiz. "The Kardashian's ,Khloe, Kourtney and Kim with mum Kris Jenner and step-sister Kylie, are a hardworking family", says Oprah Winfrey. But Winfrey was full of praise for the reality TV stars when asked by the very same radio duo to share her thoughts this morning. Oprah commented: "I disagree that they don't do work, I think that they have become their own iconic phenom in this country and overseas, and you don't get by not doing a few work, you just don't".
