Kim Kardashian Attacks Rob Kardashian In 'KUWTK' Preview, Talks 3rd Baby & Flaunts 70-Lb Weight Loss In Sheer Frock

Beware Kim Kardashian when she's furious. A new sneak peek of Keeping Up With The Kardashians shows that the 12th season will reveal what happens when Kim gets angry. And the most recent reason for an explosion from Kardashian has to do with her discovery that her brother, Rob Kardashian, is engaged to Blac Chyna, reported the Daily Mail.

Kylie Jenner observes as Kim verbally attacks her brother.

"You make sure your girlfriend doesn't publicly bash your sisters!" screeches Kardashian.

Kim had also previously issued an order to Rob.

"I'm not going to let my sister get disrespected, it's just not what our family does," declared the mom-of-two.

What's not shown in the preview is that Kylie (currently dating Tyga, who is the former fiance of Chyna, as well as the father of her son) felt betrayed by her brother, with Kim making the decision to defend her little sister.

However, momager Kris Jenner seemed to take the news calmly.

"Welcome home," she told her son.

Stirring up her own brouhaha is Kourtney Kardashian, who got upset with Tyga because she blames him for enabling her baby daddy, Scott Disick, to drink and party.

"I almost want to call Tyga and just literally go off on him," declared Kourtney.

It hasn't even been six months since Kim and Kanye West (and their daughter North) welcomed baby Saint into the world, but Scott Disick is shown in one of the KUWTK previews questioning Kim about whether she wants a third child.

"Kanye has said it every single day," admits Kim. "I don't think I can carry another one."

Rather than plan a third pregnancy, Kardashian has been focused on weight loss. Kim revealed earlier this year that she had chosen the Atkins diet to shed 70 pounds, and recently shared her pride in her weight loss success on social media.

"YOU GUYS!!!! PRE BABY WEIGHT WAS 135!!!!!" gushed Kim.

"Gunnar is amazing!" praised Kim. "He has a private gym where we just grind, grind, grind!!! I put in the work and I definitely see it paying off."

As for the possibility of a third baby? In addition to her stress about her weight, Kim already has had pregnancy problems. She had IVF treatments, and worried that placenta accreta would require a hysterectomy. Because both of her pregnancies were risky, her physicians have told her that attempting to have a third baby "could be dangerous," an insider revealed to People.

Kardashian fans can mark their calendars for Sunday, when Season 12 of Keeping Up with the Kardashians debuts.

But those who want to check out just how Kim looks after her weight loss don't have to wait.

Kardashian flaunted her post-baby body in a skin-tight sheer red Balmain dress at Naomi Campbell's book signing, noted ET.

However, Kim didn't neglect the famous supermodel, showing that she's a fan and sharing that she even requested a signed copy of the book for little North. Kardashian chose a photo that showcased both her own weight loss and Naomi's beauty.

"So proud of @iamnaomicampbell on the launch of her new book!" wrote Kim on Instagram. "Looking at these collection of images is so inspiring! Thanks for signing a book for North! Love you!!!"

In all, Kardashian has succeeded in a 70-pound weight loss, according to the Daily Mail.

Among her recent photos is one showcasing her newly toned legs, with her glam squad surrounding her.

"Set vibes," wrote Kim as her hair stylist worked on her.
