[article id="1687123"]Oprah Winfrey's highly anticipated sit-down with the Kardashians[/article] is set to air on OWN on Sunday, on "Oprah's Next Chapter." Now, leading up to the interview, fans are getting some sneak peeks at what the talk-show host got the first family of reality TV to dish about.

"I think that's so ridiculous," Kim told Winfrey when asked if she ever feels exploited by her manager and mother, Kris Jenner.

"First of all, we have to hire a manager. So regardless, someone is going to get that [job]. No one will fight harder for you than your own mother," she said, according to

In true Oprah fashion, Winfrey asked all the hard questions, including getting Kim to open up about her [article id="1673430"]short-lived marriage to Kris Humphries[/article]. "Everyone who's asked was the marriage a publicity stunt? Why did she leave after 72 days? Her answer leveled me," Winfrey said on her Facebook page.

"Ok my friends I had the longest interviewing session I can ever recall, talking to ALLLLLLLL the Kardashians. I had never met them, nor seen the show," Winfrey blogged. "I did a full on Kardashian Kram in preparation, watching major shows from every season. I genuinely wanted to know why they have become a cultural phenomenon? Why do so many people love to watch their every move and why do so many others love to hate them. Are they completely ego centered? Are they really 'famous for being famous' or is there something more?

"I 'GOT IT' ... those answers + more," she added. "Those of you who watch the show know they hold nothing back. This interview I'd say was another level of forthrightness and honesty. Who surprised me the most? Scott. Lamar and Khloe. Kim."
