Kim Kardashian admits hearing what Kourtney says behind her back while editing 'The Kardashians' causes 'tension' to rise again even after they've made up

• Kim Kardashian said that sometimes editing "The Kardashians" can lead to rising tensions.
• She said that she'll see what her sister Kourtney said about her (and vice versa) during editing.

Kim Kardashian says that the editing process for "The Kardashians" can rehash some tension from filming, such as between her and her sister Kourtney Kardashian Barker in the show's upcoming season.

Kardashian appeared on the "Today" show on Tuesday promoting both her Skims pop-up at Rockefeller Center in Manhattan and the upcoming third season of her family's Hulu series "The Kardashians." Speaking with host Savannah Guthrie, Kardashian spoke about the tension between her and her sister Kourtney Kardashian Barker that's been teased in a trailer for the new season.

While Kardashian said that she and Kardashian Barker will "always be okay," she said that living their lives through a reality show can sometimes require them to rehash drama.

"You film it, and then months later, we think we're good and we make up, and then you edit it," Kardashian said. "And then I'm seeing all the things she's saying about me behind my back, and she's seeing all the things I'm saying about her behind her back. The tension rises all over again."

The trailer for the new season teases conflict between Kardashian and Kardashian Barker. In the trailer, Kardashian Barker claims that Kardashian used her wedding "as a business opportunity," while Kardashian says in the trailer that she "couldn't have been more mindful." Kardashian and Kardashian Barker have previously had conflicts on their prior reality series "Keeping Up With The Kardashians," including one disagreement that culminated in a physical altercation.

Kardashian also told Guthrie on "Today" that this season of "The Kardashians" was her "most emotional and frustrating internally with family," out of all 15-plus years of her time doing reality television. And eventually, she and her family will go through the drama of rehashing it all again once season three premieres on May 25.

"It is a cycle. I think I like to look at it as therapy, how to like, get through it, but it gets really tricky and it gets really emotional," she said. "But at the end of the day, we still love sharing our life, and I don't see that changing any time soon.
