Rob Kardashian Doesn't Think His Family Has Been "Welcoming" When It Comes to Blac Chyna

Kris Jenner has a new problem to solve.

It's no secret that Rob Kardashian's mother and sisters haven't been the most supportive of his relationship with his pregnant fiancée, Blac Chyna. On this Sunday's episode of Keeping Up With the Kardashians, it looks like Rob will finally be calling his family out for their lack of approval.

In the clip below, Kris Jenner sits Rob down to talk about how his relationship with Blac Chyna has affected his relationship with his sisters, particularly Khloe Kardashian, who he was once extremely close with.

"Y’all aren’t, like, that welcoming of this relationship, so you can’t just expect me to be like, 'Oh, let’s all hang out. Everything’s cool and fine,'" Rob says, in the clip.

Jenner plays the cool, calm, and collected mother role, telling Rob, "It's nice if you still have a bond with your family because we all love you so much. And I want you and Khloe to be okay and happy and connected. She's your sister, you know?"

Ultimately, Rob agrees to reach out to Khloe, but we can't help but wonder how much of this family tension will spill over into Rob & Chyna, which premieres on September 11. (Judging from the trailer, there will be plenty of drama.)
