It looks like the family feud between the Kardashians and Blac Chyna has settled down. Blac Chyna and Rob Kardashian attended Khloe Kardashian's birthday party and all seems totally cool.

Kim posted a photo to her instagram account of she and Chyna playing air hockey together. On this past sunday's episode of "Keeping Up..." Khloe said no one should congratulate" Rob on his engagement to Chyna, however, these recent photos seem like everyone is really getting along.
