Brody Jenner is feuding with Caitlyn Jenner and may not attend the Excellence in Sports Performance Yearly Award (ESPY) next month, where the latter will be honored, Radar Online reported. Brody, who was reportedly the first person to support Caitlyn with her decision to transition into a woman, is upset over the 65-year-old’s plans for a docu-series.

In her interview with Vanity Fair, Caitlyn had discussed about Brody and his siblings’ decision to opt out of the docu-series. Brody is “still very hurt about the comments” that Caitlyn made during the interview, a source told Radar Online.

“Brody had been extremely supportive of everything that she had been doing,” the source reportedly said. “Long before Kim [Kardashian] publicly embraced it, he was there.

“Brody just doesn’t want to be a part of the publicity circus,” the source said, adding that if things are not resolved between Brody and Caitlyn, then the former may not attend the ESPY Award, where Caitlyn is scheduled to receive the Arthur Ashe Courage award. Caitlyn’s family members are reportedly expected to join her onstage when she will receive the award.

Earlier this month, reports surfaced that Rob Kardashian may also skip the ESPY Award. However, the reason behind his decision is not Caitlyn but his own appearance. In May, reports had speculated that Rob had checked into a Florida rehab facility that specializes in drug and alcohol addiction.

“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,” a source had told Radar Online.

The 2015 ESPY Award will air live from the Nokia Theatre in Los Angeles at 8 p.m. EDT on July 15 on ABC.
