Caitlyn Jenner Wasn't Trying to Diss Kim Kardashian with 'Calculated' Remark

Caitlyn Jenner wasn't trying to fire shots at Kim Kardashian when she said the mogul "calculated" her way to fame -- in fact, her comments were part of a bigger convo, where she spoke proudly of Kim.

Here's the deal, Caitlyn's featured in the trailer for the upcoming docuseries, "House of Kardashian," which dives deep into the family's rise to fame. In the first look, which came out last week, Caitlyn says, "Kimberly calculated from the beginning, 'How do I become famous?'"

While it seemed like a dig, sources close to Caitlyn tell TMZ ... her use of the word "calculated" wasn't the best choice, but it's already been relayed to Kim she didn't mean it as a diss.

We're told the explanation given to Kim, after the trailer dropped, was that Cait's words were edited to come off more controversial than they actually were... it's a promo, after all.

One source added, Caitlyn's proud of Kim, and thinks what was shown in the 40-second clip isn't reflective of her actual intentions when she sat down to discuss her ex-wife and children.

Caitlyn was only a contributor on the Sky-produced series, so she has no creative control over what makes it into the final edit from her interview ... but we're told she agreed to talk with producers, intending to be a positive voice to defend her family's legacy.
