All-new episodes of Keeping Up with the Kardashians return Jan. 7 at 9 p.m. ET on E!

After months of speculation and subtly dropped hints, it looks as if we might finally get a pregnancy announcement from Khloé Kardashian.

At the very end of a new midseason supertease for Keeping Up with the Kardashians, the family gets together with a bustling group of friends, throwing what appears to be a party at one of their homes. Suddenly, a chorus of shocked exclamations erupts, hinting at some major news.

“Did you not know?” Kim Kardashian West asks Kris Jenner excitedly as her mom dissolves into tears and responds, “No!”

“Oh my God!” squeals Kourtney Kardashian.

“Are you kidding me?!” demands another guest as Khloé’s BFFs Malika and Khadijah Haqq wrap their arms around the mom-to-be for a hug. (Multiple sources have confirmed to PEOPLE that Khloé, 33, is expecting her first child, a baby boy, with her boyfriend Tristan Thompson, 26, though the family has yet to publicly comment on the news.)

But that’s not the only bombshell the promo teases. While 20-year-old Kylie Jenner — who is also pregnant and expecting her first child, a baby girl, with her boyfriend Travis Scott, 25 — is noticeably absent from the entire video, she does make a behind-the-scenes appearance in the form of a phone call to mom Kris.

“Hi, Kylie,” says Kris, 62, answering the call while taping a confessional. Seconds later, her mouth drops and she exclaims “What?!” before getting up abruptly.

“Should we have her arrested?” she can be heard saying as she walks away.

The promo also hints at drama between Rob Kardashian, 30, and his ex-fiancée Blac Chyna, 29, over custody of their 1-year-old daughter Dream, and a strange confrontation between Khloé and Kris’ boyfriend Corey Gamble, 37.

“Lately, things have been weird between us,” she tells him over a tense meal. “I don’t even know what this is.”

But Thompson is quick to defend his girlfriend.

“You’re the pitbull in the family,” he tells Khloé in another scene. “Nobody likes to ruffle your feathers.”

The supertease also features an emotional Kendall Jenner, 22, who reveals her struggle with anxiety, prompting Kris to offer to take her to the hospital.

And amid all the drama, the momager herself puts it best: “I swear to God,” says Kris, “I’m going to lock myself in a funny farm.”

The midseason finale of Keeping Up with the Kardashians airs this Sunday, and all-new episodes return Jan. 7, both at 9 p.m. ET on E!
