, Kim, 42, admitted that she and her family have not been in the same room together for some time.
"The Kardashians have not been together as a family in a while," she confessed.
The trailer clip continued on to show the tension rising between the Skims founder and Kourtney, 44, who has accused her sister of using her wedding to Travis Barker as a "business opportunity."
KOURT'S FEELINGS
Earlier this week, the mother of three opened up about her feelings toward her family's "superficial" relationship in another new preview video for The Kardashians.
The Keeping Up With the Kardashians alum was seen having a conversation with sister Khloe Kardashian during the new season.
In the preview clip, Kourtney opened up about how the family rallies around one another in times of crisis, although she feels like it happens in a "superficial way."
"I don't think we know how to like be there for each other on like a deeper level," Kourtney said.
"I think I do," Khloe responded, clearly shocked by the bold statement.
In her confessional, Khloe continued: "When there's something pretty traumatic or devastating in the family I feel like we're all by that person's side.
That's my experience and if Kourt doesn't feel that way then I feel badly for her."
SNUBBING KHLOE?
The Good American founder also claimed Kourtney was in her "love bubble" after her recent marriage to Blink-182 drummer Travis Barker, further saying she never checked in with her "about the baby."
Khloe's ex and baby daddy, Tristan Thompson, had an affair and welcomed a son named Theo with Maralee Nichols in December 2021 when he was supposedly mutually exclusive with Khloe.
News of the cheating scandal came after Khloe and Tristan's surrogate was already pregnant with their second child, Tatum.
While Khloe clearly had some beef with Kourtney over her level of support, Kourtney's "superficial" comment also came amid her feud with Kim.
Trailers for Season 3 of The Kardashians have shown the Poosh founder "livid" with her younger sister.
KIM VS. KOURT
During a recent interview with , Kim confessed: "This season was probably one of my - out of filming Keeping Up With the Kardashians or The Kardashians - this season was probably my most emotional and frustrating internally with family, that I haven't really seen or experienced before."
Savannah asked: "Why is that? They talk about some tension between you and your sister Kourtney over her wedding. Is that the source of it?"
"Yeah - and we've been there before and we'll always be okay. We're always family, that's how we were raised.
"But I'm also proud that everyone's really vulnerable because I'm sure so many other families have gone through similar things.
"Maybe on different levels or experiences but I'm proud that we're still so open and still driven to show and share so much," she admitted.
Fans have speculated that Kourtney and Kim have been at odds since the eldest Kardashian tied the knot with Travis in May of 2022.
