Here's why Caitlyn Jenner's first four children refuse to appear on her new E! reality show

Caitlyn Jenner's first four children support her decision to live life as a women, but they're refusing to be part of her upcoming reality show for E! Entertainment.

According to the Vanity Fair cover story, Caitlyn's four children (all in their 30s) born from Caitlyn's two marriages previous to Kris Jenner - Cassandra, Burt, Brandon, and Brody Jenner - won't appear on the show because they fear that E! and the show's producers, Bunim/Murray, will sensationalize Caitlyn's story.

"They disagree with their father's decision to use not only the same production company that made 'Keeping Up With the Kardashians' but many of the same people, including several original executive producers," the article stated.

Hurt and disappointed by their decision, Caitlyn argued that as an executive producer she can keep it from straying away from her desire for the show to tell her story in a way that will be inspiring and informative. The four kids doubt that's possible.

"You go on E!'s web site, the Bunim/Murray web site, and you look at all the shows, every one of them is a circus," Brandon Jenner said during a meeting over hiring a new producer.

He continued, "With Bunim/Murray and E!, it's been the opposite of inspiration. Oh my God, we're diving into the lion's den - they're gonna make a show about the Jenners versus the Kardashians."

Certainly, bad blood does exist between the four children and Kris Jenner, according to the article.

They feel Kris not only excluded the Jenner side from "Keeping Up With the Kardashians," but further created distance between them and their father. They also had to watch as Bruce became an ideal dad to the Kardashian children, something they had always wanted from the often absentee dad they experienced growing up.

E!'s head of programming, Jeff Olde, told the magazine that he hopes the Jenner side will change their minds once they see "the quality and tone" of the new reality show.

"It's not at all a Kardashian spinoff," he said. "We will not resort to spectacle. That doesn't mean we can't have fun with it."

Gay and married, Olde has been a fighting for gay rights for two decades. "This is so far beyond television, on a personal level," he insisted. "If I get one thing right in my professional career, it will be this.

Additionally, Bunim/Murray's executive vice president of development and programming insisted "ratings are not the goal." "It is to tell Bruce's story the way he wants to be told," he said.

The reality show started shooting in May and premieres Sunday, July 26 at 9 p.m. on E!
