But although the entire Kardashian clan took to their social media to share support for thee 65-year-old, Kris Jenner's voice was noticeably absent. And now, a source close to the family tells RadarOnline.com exclusively that Kris' silence was because she is jealous!

"Caitlyn's instant rise to fame and support has everyone now focused solely on her and not on the Kardashians anymore," the source tells RadarOnline.com, adding that "this was Kris's biggest fear."

According to the insider, "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 RadarOnline.com previously reported, Jenner made her debut on the cover of Vanity Fair magazine, titled "Call Me Caitlyn," after she recently allegedly underwent several feminizing facial procedures, as well as a breast augmentation and sex change operation.

"Already Caitlyn is more beautiful than Kris and more beloved by fans, and this has Kris spinning out in her head," the source tells RadarOnline.com.
