The members of the Kardashian-Jenner clan are not that outspoken about their support for Caitlyn Jenner, but there is a reason for that.

On the first day of the ITV series "I'm A Celebrity... Get Me Out Of Here," Caitlyn already felt homesick, so much so that she cried in the middle of the night and contemplated if she is doing the right thing.

Despite the issue making headlines, the Kardashian-Jenners failed to show Caitlyn some love when she needed it the most.

Her fans lambasted her family even more after Caitlyn received an underwhelming care package from her dogs. Even though the 70-year-old decided to look at the brighter side, her fans and viewers felt gloomy and saddened over what happened to her.

People also criticized the Kardashians and Jenners, most especially Kylie Jenner and Kendall Jenner, for not paying attention to their dad.

Despite all issues, though, it appears the Kardashian-Jenners have their reasons why they are not publicly supporting Caitlyn.

A source told MailOnline that Caitlyn's family found it hard to watch her participate in the series since she is the complete opposite of the character she is showing right now.

"Caitlyn is being completely herself in the jungle and that is why the public is loving her. She is extremely kind and generous so it's no surprise that she isn't involved with any of the arguments in the jungle!"

The insider also stated that the clan has been truly watching her from home and felt shattered when Caitlyn broke down in tears at the start of her journey, wanting to finally quit for the first time.

Caitlyn's Mom Cannot Watch It

Esther Jenner refused to watch the ITV series and compared it to the U.S show "Survivor" (which she also never watched since she really "does not care about that").

The Jenner matriarch does not want to watch it due to the same reason: it hurts her in every way possible to see Caitlyn suffer.

Esther affirmed that seeing her daughter try to defeat the dreaded "Bushtucker Trials" and lead all the celebrities looked like a "torture" to her. She also believed that Caitlyn should spend her time playing golf instead of joining in the series, just so she could also avoid getting worried about her.

Kendall, Kylie Speak Out

After a few days of heavy criticisms, both Kendall and Kylie displayed their support for Caitlyn by liking posts related to their dad.

Kendall liked a video of Caitlyn dancing to the "Girls Aloud" dance routine together with her co-celebrities Nadine Coyle and Jacqueline Jossa. She also added that not because she is not posting anything about her dad, it does not mean she does not want to support her.

Meanwhile, Kylie, who recently sold 51 percent of her Kylie Cosmetics company, showed her support by interacting with Caitlyn's post with her dogs and Sophia alongside the caption, "We are all rooting for you @caitlynjenner on @imacelebritylive on @itv."

Caitlyn's Instagram page is currently being run by her close friend Sophia Hutchins
