What just happened? Whatever it is, it looks really suspect. Perhaps, it's just another Kris Jenner production, or maybe all's fair in love and war.

Blac Chyna and Rob joined Kourtney, Kris, Kylie, Tyga, Scott and Kim for an outing at Dave and Buster's in Hollywood for Khloe's 32nd birthday party.

The sisters let the claws out when they found out about Chyna and Rob's engagement on this week's "KUWTK," but now it appears their beef with the sometimes model was squashed.

As is customary in these times, the treaty was shared on social media. Chy, Kim and Kylie took precious selfies for Instagram and Snapchat showing that they're one big happy family. Literally, Chyna posted a touching pic on Instagram with future mother-in-law, Kris Jenner and captioned it, "So much fun with Mama @krisjenner." Jenner features a big smile — of course — because where there are Kardashian expansions, there are E! negotiations to be made.
