It's another day, and there's another drama in the Kardashian-Jenner family. Surprise, surprise? I think not.

Brody Jenner - the 34-year-old son of Caitlin Jenner and Linda Thompson, and half-brother to Kendall and Kylie Jenner - has revealed that his little sisters, Kendall and Kylie, never RSVP'd to his wedding. And naturally, the internet finds it all kinds of awkward.

Brody, an American television personality and model, is due to marry his fiancée Kaitlynn Carter, next month. And in an interview with People, he disclosed that Kylie and Kendall Jenner never even bothered to respond to their wedding invitation. "My two little sisters, we never even heard from them. They never even RSVP’d I don’t think," he said. "We sent them an invite but we just never heard anything back."

Although we'd be pretty peeved if our siblings didn't reply to something as significant as a wedding invitation, Brody kept things diplomatic, saying that Kylie and Kendall would be "missed", and that he'd "have loved to have had them there."

However, this is not the first time that the beauty mogul and model have kept their half-sibling out of the loop. Back in February, Brody told TMZ that it had been "a couple years" since he'd seen Kylie, and he even revealed that he "didn’t even know she was pregnant for the entire pregnancy".

I guess that only certain parts of the Kardashian-Jenner klan are as tight as they're made out to be in Keeping Up With The Kardashians...

But as well as Kylie and Kendall, it appears that Brody's biological father, Caitlyn Jenner, will also be unable to attend his upcoming nuptials.

An inside source close to both Caitlyn and Brody revealed to People that "Caitlyn has work commitments that have been set up for months and couldn’t be changed in the end." But aside from the scheduling conflicts, the source alleged that "everything is good between them." "She will be throwing a big party for them when the newlyweds return to town," the source continued.

However, it's evident that Caitlyn enjoyed being part of her future daughter-in-law's bachelorette party in April. "Went to my first bridal shower, for Brody's fiancé Kaitlynn Carter. I had so much fun!" she wrote on Instagram. "PS so much better than Bachelor parties!"

Brody, who starred in MTV's The Hills, proposed to 29-year-old Kaitlynn Carter in May 2016 after two years of dating. "I couldn’t be more in love with this woman and I can’t wait to spend the rest of my life with her," Brody asserted at the time.

The couple is due to tie the knot in Indonesia on Sumba Island at Nihi Sumba, but another inside source has claimed that "there is an LA reception that’s going to be planned, so maybe that’ll be different".

Well, fingers crossed that Kylie, Kendall and Caitlyn can all come out and support their family at this special time.
