Kris Jenner is secretly planning to steal Caitlyn Jenner’s big moment at the Excellence in Sports Performance Yearly Awards (ESPY) next month by moving the spotlight on her son Rob Kardashian, Radar Online reported Wednesday. Ex-Olympian Caitlyn, formerly known as Bruce Jenner, will receive the Arthur Ashe Courage Award on July 15.

Kris reportedly wants Rob, who has been avoiding the public due to a massive weight gain, to debut at the event in a healthy shape to draw away the attention from Caitlyn, a source told Radar Online. Caitlyn’s family members will reportedly join her onstage when she will receive the award. However, the source added that it was not clear if Rob would be of any help to Kris’ plan as he has “no interest in going to the ESPY awards and going on stage.”

“Rob fully supports Caitlyn, but remains in a dark place and doesn’t want to go out in public because he isn’t comfortable with his physical appearance,” the source reportedly said.

The “Keeping Up With the Kardashians” matriarch has reportedly pressured Rob to make a drastic change in his appearance before the event and has also set up training sessions for him. “But he has shut it down,” the source reportedly said. “Rob will get back on track according to his terms, and no one else’s.”

Rob was ​reportedly unaware about Caitlyn’s debut until his sister Kim Kardashian West sent him Caitlyn’s cover of Vanity Fair via text message.

“It was so funny because all the girls, we knew that Caitlyn was shooting this but my brother had no idea,” Kim, 34, told Access Hollywood. “So I sent it on a mass text to everyone and my brother was on it and he goes, 'Kim, why are you sending me this? Who is this woman? And why do I care?'”

In April, Rob had shown support for Caitlyn in a tweet after she revealed to Diane Sawyer -- before her transition -- about her gender identity.

The 2015 ESPY Awards will air live from the Nokia Theatre in Los Angeles at 8 p.m. EDT on July 15 on ABC. ESPN announced earlier this month that Caitlyn will receive the Ashe award, which goes “to individuals whose contributions transcend sports.” 

Following the announcement, Caitlyn said: “For the first time this July, I will be able to stand as my true self in front of my peers.”
