Kim Kardashian and Blac Chyna Call a Truce, Joined by Rob Kardashian hanging out for launch

Kim Kardashian and Blac Chyna have buried the hatchet.

Kim and Blac were spotted around Beverly Hills with Rob Kardashian Tuesday, and based on Rob's large smile it appears to have been a very friendly reunion! The Keeping Up With the Kardashians stars and Blac ate brunch at Nate 'n Al before tending to some other errands.

An eyewitness tells E! News that their visit, which doubles as the first time Kim and Blac have been spotted together since Rob announced the engagement, was completely cordial. "They...were really just so nice! Rob used to come in all the time and he hasn't been here a while. He was always the sweetest. All the Kardashians come in and they've always been nice," the eyewitness tells us.

The betrothed couple and Kim enjoyed their meals without any apparent awkwardness.

"Kim and them were just sitting at a booth and they looked like they were having a good time," the eyewitness says. "They were talking directly to each other, not looking away or anything, so they were engaged in a conversation all of them. Everyone seemed happy and they were really nice."

Kim and Blac's reunion comes only a little while after Kylie Jenner and Blac's meet up. Fittingly, it was Kim who encouraged Kylie and Blac to work out their differences. "Kim and Chyna have a history and they thought it would be a good way to break the ice with all involved," another source previously told E! News. "It didn't take too much convincing for [them] to meet. They both wanted to have a sit down for a while now anyway."
Kylie and Blac kicked off their truce by discussing Rob's happiness, which is of the utmost importance to both of them. They also discussed Tyga, as he's the father of Blac's child and Kylie's boyfriend. Now that Blac and Rob are set to tie the knot, the Lashed owner is "very excited" to officially become a Kardashian.
"She always loved them and was very close to the family before they all had a falling out," an insider said. "Kim was like a sister to her...Blac 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."
