But now, the 33-year-old E! star has been caught in a major contradiction which is at the center of the family's courtroom battle with their ex-stepmom: Despite momager Kris Jenner claiming in a sworn court declaration that the family isn't responsible for editing on any of their reality shows, mother-of-one Kim has previously admitted she has final say on what airs!
Jenner made the new claim about her supposedly hands-off approach to editing in a revealing declaration that she filed as part of an effort to have a defamation lawsuit that was filed against her and her children by Robert Kardashian's widow, Ellen Kardashian, thrown out of a Los Angeles court.
In the document, Jenner protested that after episodes of their E! show are filmed and edited, the family provides "comments and suggestions" to producers at Bunim-Murray Productions, Inc., but she insisted that they are not "responsible" for the editing.
"I hold the title of President of Jenner Communications, Inc.," Jenner asserts in the text.
"Jenner Communications, Inc., (JCI) is and acts as the management company for the Kardashian/Jenner/Odom/Disick families. JCI contracts to provide there personal services of myself to E! for the show. JCI is not a producer of, nor does it receive any producer credits for or related to, the Show."
"JCI, myself, and my family members, that are the subject of the show, are not responsible for the editing or the production of the show," she claims. "After episodes are filmed and edited, we are provided the opportunity to provide comments and suggestions to BMP as to footage in a particular episode that has been filmed from or about our lives and BMP does take those into account."
Jenner has subsequently claimed she does not have final control over what airs.
But in 2011, during an interview with CNN's Piers Morgan, Kim boasted about having editorial control!
"I mean, I'm really particular on what I show about, you know, any relationship that I may have," she said. "Or there are so many personal things. And what's so cool is our relationship with the show is from the start, they've always said we have, you know, the right to edit and to approve all the footage."
But in another interview, conducted in 2010, Jenner provided more context about their role in the editing process.
The manager/mother said as Executive Producer, she "edited" scenes that she wanted too but stopped short of describing their influence as Kim chose to.
Discussing the notorious scene of Kendall and Kylie Jenner dancing on a stripper pole during the first season of Keeping Up With The Kardashians, Jenner was asked by ABC anchor Christine McFadden if "as an executive producer, she let it go out there."
"Yes, I did," Jenner, 58, admitted. "And in my first season, I probably, it would have been one of the things I edited. But I didn't."
Two years later, she insisted yet again that she holds some reigns -- but not all -- of the show, admitting to the Wall Street Journal Digital Network: "I have been offered the opportunity to actually go back and edit things out."
A legal representative for the Kardashians told Radar: “Ms. Jenner's statements are accurate and consistent with prior statements."
"The Kardashian's are 'not responsible for the editing or production of the Show,'" the spokesperson added, quoting the court filing.
"After the production company films and edits the footage from or about their lives to create a particular episode, the Kardashian's are allowed the opportunity to provide input and make comments as to captured footage, and BMP 'does take those into account' in editing.”
Stay tuned to Radar to see if Kim's contradiction comes up in court. The next hearing to see whether a judge will dismiss Ellen Kardashian's lawsuit is on December 17.
