Brody Jenner reportedly banned Kim Kardashian West and Kris Jenner from his birthday bash

A source told gossip website RadarOnline.com: "His girlfriend, Kaitlynn Carter, his dad Bruce [Jenner], his mom Linda Thompson, brother Brandon, and of course younger sisters Kendall and Kylie were there. Kim, and his step-mom, Kris Jenner, were noticeably absent.

"But there was never any thought to even invite Kim. Publicly the two will say there is no feud, but that is all for keeping up the appearance of having a big extended family for the sake of the E! reality show."

The duo are said to have fallen out because Kim refused to invite Brody's girlfriend to her nuptials.

The insider added: "Brody never sees Kim except when they are filming, and the two aren't even considered friends."

To add insult to injury, Kim and Kris had lunch with her sisters, Khloé and Kourtney Kardashian, at the same venue just hours before Brody's party.

The source said: "Kim has often joked about wishing she could move into the hotel because she feels so at home there."

After he attended Kim's ex-boyfriend Reggie Bush's wedding in July, Brody admitted he skipped her wedding because he doesn't know Kanye "at all" and claimed he had to work.
