Time for the big reveal! In December, Khloé Kardashian confirmed via social media that she is indeed expecting a baby with boyfriend Tristan Thompson, and now it looks like we’ll finally get to see the moment the whole family found out.

The latest Keeping Up With the Kardashians teaser promises a two-part special dedicated to covering big goings on in the KarJenner house. “When it comes to making announcements, the family’s got news so big, we need Sunday and Monday just to cover it,” the voiceover in the promo says.

At least one of the big announcements, it seems, is Khloé’s pregnancy reveal to her family, as first suggested in a previous teaser. In the clip, the Revenge Body host is seen walking into a backyard afternoon party to some pretty shocked reactions from Kris Jenner, Kourtney Kardashian, BFF Malika Haqq, and more.

It’s possible the January 14 and 15 episodes could also feature Khloé revealing the sex of her baby, which she confirmed she would indeed be doing on the show. So far, the denim designer says she and Thompson have agreed on the name Junior if they have a boy, but remain stalled on girl’s names.

So what more could be in store on the show? Some fans are speculating that Kylie Jenner could also be using the two-part episode to address her rumored pregnancy for the first time. While the youngest Jenner sister doesn’t appear in person in the clip, she can briefly be seen FaceTiming in the trailer, and reacting excitedly to something one of her family members has told her — or maybe delivering her own exciting news?! We’ll have to watch this Sunday and Monday to find out!

KUWTK‘s two-night special airs on E! Sunday, January 14, and Monday, January 15, at 9pm ET. In the meantime, check out the latest teaser below.
