Kim Kardashian West is not a fan of social media bashing.
In a sneak peek clip from an upcoming episode of Keeping Up With the Kardashians, the 35-year-old reality star slams her brother, Rob, and his fiancée, Blac Chyna, for publicly dissing her famous family on the Internet.

"Hey Rob, look, I never get p**sed and I am so for you being happy, but whatever Chyna and Kylie [Jenner] and all the drama that they have together, like, that's for them to work out," Kim tells Rob over speakerphone as her youngest sister, Kylie, listens in. "[And] mom has bent over backwards doing all this stuff."
The clip then cuts to a solo interview with Kim, who explains that Kris had told her Rob was "making fun" of her for the types of food she had purchased for his new home.
"I mean, my mom literally just helped him move into a new house," she adds. "I have to call my brother out on this, like, there's no way I'm going to let my brother disrespect her."
"Mom is p**sed," she explains to her 29-year-old brother. "When you start publicly bashing my sister and mom, that's not cool. This is just unnecessary."

"This is not what our family does," Kim continues. "There's way too much drama, so many haters in the world, we don't need it from our own inside circle."
Rob, who is expecting his first child with Chyna, finally chimes in, claiming he "didn’t even know what was going on." He also notes that he doesn't think any of it was that serious anyway.
Things get heated, and Kim starts to yell at Rob, insisting that people (aka him and Chyna) really need to stop bashing others over social media.
"You [and Chyna] are a unit now, so it looks like you're blasting mom, and it's petty as f**k."

While there's been a lot of "blasting" incidents between Chyna and the Kardashian-Jenner crew ever since she and Rob became a couple in January, Kim seems to be referring to that time when the 28-year-old model poked fun at Kris for stocking her fiancé's new kitchen with healthy food via Snapchat.
"Baby, what's in your cabinet?" Chyna asked, as she panned her camera phone over fat-free sorbet, a bucket of I Can't Believe It's Not Butter, Irish oatmeal and organic quinoa. "What the f**k? Nah, nah. Babe, what is that? Are we supposed to eat this?"
And although Kim doesn't tell us exactly what Chyna-Kylie moment she's talking about in the clip, we have a good feeling she's referring to the not-so-subtle shade Chyna threw at Kylie for her new cooking series, Cooking With Kylie. Back in February, Chyna -- who shares a 3-year-old son, King Cairo, with Kylie's ex-boyfriend, Tyga -- took to Instagram to seemingly call out the 18-year-old lip kit maven for copying her idea.

"B**ch Bye," Chyna captioned a screenshot of one of her other social media accounts, which consists solely of cooking snaps. "Follow @cookingwithchyna #InfatuatedWitChy."
