The trailer for "The Kardashians" confirms the viral theory that Kim and Kourtney Kardashian are engaged and the relationship between them is not the best possible.

A new trailer for "The Kardashians" season 3 apparently confirms that Kourtney and Kim Kardashian had a fight after Kourtney married Travis Barker.

At one point, Kendall asks Kim, "Have you talked to Kour about [the incident in] Milan?". Kourtney, in another scene, says, "My sister used my marriage as a business opportunity."

Kendall then adds that "Kourtney felt like they ruined the atmosphere of the wedding" implying that some events have had a negative impact and Kourtney has not experienced the true happiness of the party.

Afterward, Kim says, "I'm really confused as to how he came up with this narrative."

As for Kourtney, she says, "People think it's a misconception. It's not. That's just who she is."

If you remember, Dolce & Gabbana was heavily rumored during Kourtney's wedding in May 2022. It was even speculated that the brand sponsored the wedding - but the designers denied this claim. However, it is estimated that the wedding weekend brought in "$25.4 million in media impact value" for D&G.

The sisters dressed in D&G. All this happened in May, while in September, Kim collaborated with D&G at Milan Fashion Week. Their relationship is still going strong. In fact, Kim was the face of their Spring/Summer 2023 campaign.

So it seems that Kim's relationship with Dolce & Gabbana after (or even during) Kourtney's wedding is the cause of their feud.

Season 3 of "The Kardashians" will air on May 25 on Hulu.
