Oprah Interviews the Entire Kardashian Clan [VIDEO]

"Would you be where you are had there not been a sex tape?"

Oprah asks this of Kim Kardashian during an interview that will be airing Sunday night on OWN.  Oprah's Next Chapter features the former talk show host sitting down with every member of the Kardashian family for a special that will air at 7 p.m. Sunday on OWN called First Look:  The Kardashians.

Apparently Oprah doesn't hold back on any question and asks Kim if her short marriage to Kris Humphries was just a stunt. It's a question many Americans want to know and Oprah's going to ask it Sunday night.

Oprah also asks, "You're famous for ... what?"

That's my No. 1 question too!  I'm wanting to know how they answer this question.

First Look:  The Kardashians features Kim, Kourtney, Khloe, Kendall, Rob, Kris and Bruce Jenner with appearances from Lamar Odom and Scott Disick.
