A few of the important people in Kim Kardashian's and Kanye West's lives were not present for their wedding.

While it's been said that Beyonce is the reason Jay Z skipped the wedding, and Rob Kardashian was feeling insecure, there wasn't much explanation about why Brody Jenner didn't attend.

An upcoming episode of "Keeping Up with the Kardashians" explains that Brody was feeling snubbed by his stepmother, Kris Jenner.

In the clip, Kardashian takes her stepfather, Bruce Jenner, to the side and tells him that Brody is upset. Bruce and Kris have paid for Brody's brother, Brandon Jenner, and his wife, Leah Jenner.

Kardashian explains she didn't want to tell him in front of Kris because it was only going to hurt her feelings. Bruce believes that Brody is being "a little huffy," and while Kardashian agrees, she asked him to talk to him.

"I know, but I think he'll only listen to you," she said.

Kardashian added that she also turned Brody down when he asked if his "girlfriends" could attend.

"Brody has been saying that my mom has been favoring Brandon and Leah, and I just think that this shouldn't be my mom's problem," she said.

Before Kardashian took Bruce to the side, Kris revealed that Leah and Brandon would be staying in the same hotel as them.

Brody did end up attending Kardashian's ex's wedding. He posed with Reggie Bush and Lilit Avagyan at their July 12 wedding.

Some of the reasons that were previously given for Brody skipping the wedding were that he wasn't allowed to bring a guest and that he does not like Kris. Brody has said that he doesn't have a problem with the Kardashians.

He ultimately said he couldn't attend because he was busy.
