In just a few days, Brody Jenner, 34, will walk down the aisle to marry his fianceé, Kaitlynn Carter, 29, in Bali, but it seems one very important person may not be in attendance — his dad, Caitlyn Jenner. The former Olympian is reportedly missing her son's big day due to a previously scheduled commitment.

According to TMZ, Caitlyn, 68, is not going because of a "lucrative business opportunity" — most likely the 25th annual Life Ball in Vienna, Austria, which is set for this coming Saturday as well. Along with the event, Caitlyn is also allegedly skipping the nuptials because of a family divide "stemming from her marriage to ex Kris Jenner — and Brody is "extremely upset" by it. Unfortunately, Caitlyn won't be the only Kardashian-Jenner member to be a no-show.

Brody recently revealed his half-sisters Kendall and Kylie Jenner didn't even respond to their wedding invites. "My two little sisters, we never even heard from them. They never even RSVP’d I don’t think,” Brody told People on May 29. “We sent them an invite but we just never heard anything back. They’ll be missed. I would have loved to have had them there."

It was previously reported that Brody won't be inviting the Kardashians, who are Caitlyn's stepchildren and his stepsiblings, to his upcoming nuptials. "It's no secret that Brody doesn't care for the Kardashians," an insider told Life & Style. "He hates Kris and Kim the most, but really, he hates being associated with the family at all." However, fans are surprised Caitlyn won't be showing up since she and Brody have seemingly remained amicable since her transition. In fact, he's been on his father's side throughout her entire feud with the Kardashians. "Caitlyn and Brody are disgusted with the Kardashians," an insider shared with Life & Style. "They feel Kris and her daughters have done nothing but try to sabotage her."

On top of that, Caitlyn attended her future daughter-in-law's bridal shower back in early April. "Went to my first bridal shower, for Brody's fiancé Kaitlynn Carter. I had so much fun! PS so much better than Bachelor parties!" she captioned a photo of herself with Kaitlynn at the time.

And Caitlyn wonders why having a close relationship with her kids is "very tough…" Luckily, Brody's mom Linda Thompson will be there along with his brother Brandon Jenner, who is serving as his best man.
