On Sunday's episode of "Oprah's Next Chapter," Oprah Winfrey grills Kim Kardashian and the rest of her family on what, exactly, made them famous and why they think they're worthy of attention.

In a sneak peak of the interview posted on Oprah.com, Winfrey asks Kardashian, "Would you be where you are had there not been a sex tape?" and asks her if her famously hyped and infamously short wedding was a "stunt." Winfrey also asks the family: "You're famous for … what?"

Winfrey's interview with the Kardashians airs Sunday at 8 p.m. ET on OWN.
