Bruce Jenner's sex change reality show is reportedly being opposed by Kim Kardashian and the Jenner brothers. According to a report from TMZ, the eldest kids of the "Keeping Up with the Kardashians" patriarch and his famous stepdaughter might be afraid that their father will be exploited.

Many have been supportive of the former Olympian's admission that he wants to be a female, and messages of love were even posted by Kim Kardashian, as well as ex-wife Linda Thompson's sons Brody Jenner and Brandon Jenner. Even Burt Jenner, the usually quiet eldest son of Bruce Jenner with his first wife Chrystie Jenner, has reportedly been supportive.

However, the four allegedly believe that the Bruce Jenner sex change reality show might be too much, especially since he has revealed quite a lot already during his Diane Sawyer interview.

"They are warning him to slow down on revealing too much of his journey on reality TV," a source told TMZ.

"Kim and the boys think Bruce was spectacular on the Diane Sawyer special and won over millions of people in the process. His kids have gone to their dad to express their concern. They're worried Bruce's upcoming docu-series might 'de-class' what he's accomplished."

"They also urged Bruce not to do other interviews, and finish the process in private," the source added.

However, the 65-year-old reality star is allegedly set on continuing the Bruce Jenner sex change reality show.

"Bruce believes the docu-series will educate people and create empathy, so he's committed," a source explained.

According to a recent report from People, the Bruce Jenner sex change reality show will be unveiled once he is comfortable about detailing his transition.

It will reportedly air on E! network, which is also behind "Keeping Up with the Kardashians" and the family's other spin-off series.

"It will air when he is ready to be open about his transition. But he's acting more and more confident and seems very happy," an insider explained.

"He's being very smart about it and also respectful about his transition. Instead of completely shocking everyone, his changes have been subtle, and his family had the chance to slowly get used to his new looks and life."
