Kim Kardashian Masterminded Blac Chyna and Kylie Jenner's Meeting

Reality star helped her sister put the drama behind them

Kylie Jenner and Blac Chyna have put their drama behind them, and they can thank Kim Kardashian for encouraging them to do so.

A source tells E! News Kim "100-percent" had something to do with the ladies getting together on Thursday night, noting that she even talked to Kanye West—who also encouraged her meeting with Amber Rose earlier this year—ahead of time to get his nod of approval.

"Kim and Chyna have a history and they thought it would be a good way to break the ice with all involved," the source explained. "It didn't take too much convincing for [them]  to meet. They both wanted to have a sit down for a while now anyway."

The insider added that Kylie and Chyna started the whole conversation by discussing Rob's happiness—the most important thing for both of them. They also touched on Tyga, smoothing over the drama surrounding the fact that he's Chyna's ex-fiancé and Kylie's current boyfriend. Overall, they realized they have "so much in common," which the source says makes them "bound" to keep hanging out and get closer.

A second source tells us Chyna hopes this meeting will help her work it out with the rest of the Kardashian/Jenner clan, too. "She wants the family to see that she is a good fit for Rob, and she cares about him."

Now that she and Rob are engaged to be married, another source noted that Chyna is "very excited" to be a Kardashian. "She always loved them and was very close to the family before they all had a falling out," the insider said. "Kim was like a sister to her...Chyna would like to get back to where things were with them and thinks that their families will start blending more in light of the news and how happy Rob is."

In general, Chyna's main concern is Rob, and the insider says she knows how much it would mean to him if she were able to finally smooth things over with his family.

Rob has already expressed this feeling, taking to Instagram after Chyna and Kylie's meeting to repost a photo of them, writing, "So happy my girls finally got to talk and make peace! #MyFamily #AllLove."
