SYDNEY, Nov. 11 (UPI) -- Oprah Winfrey doesn't believe the Kardashians are simply "famous for being famous."
The 61-year-old media giant discussed the celebrity family in an interview with The Kyle & Jackie O Show on KIIS 1065 this week. Winfrey spoke to the Kardashians for Oprah's Next Chapter in 2012, and had nothing but praise for their work ethic.
"[People] think that, 'Oh, the television camera's just following you and that's just easy,'" she said of Keeping Up with the Kardashians. "To really create a reality series that looks like something is actually happening, it means you have to be on all the time."
"I went there to film them as a family, and I couldn't believe how hard they work," she recalled. "We were there for seven hours and they were going to tape another seven hours after we left. No matter who you are, that is work."
Winfrey's comments came just days after Rebel Wilson told Kyle and Jackie O the Kardashians "are not famous for talent." The English actress implied Kim Kardashian and her family haven't worked hard compared to herself and other celebrities.
In addition to E! series Keeping Up with the Kardashians, the family stays busy with their ever-expanding brand. Kim Kardashian and her sisters design fashion lines, own clothing stores and also profit from endorsements and appearances.
The Kardashian-Jenners -- matriarch Kris Jenner and daughters Kourtney Kardashian, Kim Kardashian, Khloe Kardashian, Kim Kardashian, Kendall Jenner and Kylie Jenner -- have starred on Keeping Up since 2007, and will return for an 11th season Nov. 15.
