"My two little sisters, we never even heard from them. They never even RSVP'd I don't think," Brody, 34, claimed. "We sent them an invite but we just never heard anything back."
"Well, they'll be missed," he added. "I would have loved to have had them there."
"Caitlyn has work commitments that have been set up for months and couldn't be changed in the end," a source told PEOPLE. Regardless, "everything is good" between her and Brody. "She will be throwing a big party for them when the newlyweds return to town."
Brody is set to marry Kaitlynn in Nihi, Sumba Island.
As RadarOnline.com readers know, Brody has been estranged from Kendall, 22, and Kylie, 20, for years. He even told reporters that he found out the Lip Kit mogul was pregnant only when he saw it on social media!
Meanwhile, Caitlyn Jenner, 68, has created quite a few enemies of her own — even within her famous family. Ever since she published her scathing memoir, Secrets Of My Life, she has been estranged from ex-wife Kris Jenner, as well as step-daughters Kourtney, Khloe, and Kim Kardashian. Not even Kendall and Kylie have fully let her back into their lives!
