Caitlyn Jenner really did break the Internet with her Vanity Fair cover, reaching 1 million Twitter followers faster than anyone in the social media platform's history.

Although most of the "Keeping up With the Kardashian" stars have shared their support for Caitlyn, it has been noticed that Kris Jenner had not openly voiced her opinion in any way.

A source close to the family has exclusively told Radar that the 59-year-old reality star and manager has been silent because she's jealous of Caitlyn. She can't believe she became so popular so quickly, which was apparently her biggest fear.

"Caitlyn's instant rise to fame and support has everyone now focused solely on her and not on the Kardashians anymore," the source said. "No one in the family was expecting Caitlyn to be as beautiful as she is. Everyone is shocked at how soft and natural she looks and, of course, Kris is just through the roof."

As "momager" of the entire Kardashian/Jenner clan, Kris feels responsible for their fame and making sure they all stay in the spotlight. She had to work hard to make sure they remained famous, and it irritates her that Caitlyn didn't have to do much.

"Already, Caitlyn is more beautiful than Kris and more beloved by fans," the source continued. "And this has Kris spinning out in her head. Kris knows that she is no longer the 'momager with the most' and this drives her absolutely nuts!"

Kris's younger sister, Karen Houghton, has revealed that it "must be hard" for Kris, according to The Washington Post.

"I don't know how Kris is doing. Poor thing. I hope Kris is okay because it must be hard," Houghton said.

Kris has still not publicly made any comments about Caitlyn.
