Kim Kardashian was seen publicly with Blac Chyna and her fiancé Rob Kardashian in Beverly Hills for the first time Tuesday, reports said, showing photos of the three of them together. Chyna and Rob have confirmed through several photos on social media that they are engaged, though an exact date for the wedding has not yet been revealed.

Radar Online said that the three went for lunch at Nate'n Al and a source close to the Kardashian family explained the reason why Kim agreed to be seen in public with Rob.

“I mean, what are they [ Kardashian family] doing to do? They are engaged,” the source told Radar Online. “They have to support their brother even if they think it is a dumb idea.”

Kim was seen wearing a black tank top and carried a plaid shirt over it.

The source also said that one of the reasons why the Kardashian family accepted Chyna and Rob together was because “a bunch of them have had dumb marriages!”

The source went on to say that Chyna has not yet filmed for their show “Keeping Up With the Kardashians.” Earlier reports said that Rob and Chyna may be working on signing a show showing their time together until their wedding for television and may air their wedding.
