Though the relationship between Blac Chyna and Rob Kardashian remains up in the air after the latter wiped his Instagram account clean, it looks like Chyna is still being accepted by her fiance’s famous family. The 28-year-old model attended the birthday party of Rob’s grandmother, Mary Jo or “MJ,” in San Diego on Tuesday.

The pregnant star stepped out at The Marine Room for the family dinner, wearing a white, long-sleeve mini dress with lace-up details. She was joined by Kim, Khloe, and Kourtney Kardashian, Kris Jenner, Corey Gamble, and Scott Disick.

The reality stars were met by a cheering crowd outside of the waterfront eatery, and filmed most of the evening for Keeping Up With the Kardashians and on their own Snapchat accounts.

“What the f**k are we doing, Khloe? I have three kids waiting and you guys are getting ready for the f**king Oscars,” Kourtney jokingly screams in one clip.

Earlier in the day, the family celebrated the opening of a Dash store with MJ.

“It’s my Grandma’s birthday,” Kim says in one clip. “We’re at our store opening.”

“Congratulations, MJ!” Kris exclaims.

North West got in on the fun, posing with her great-grandmother.

“My two fave girls,” Kim narrates one video. “Is that the kind of smile you’re going to give me? Give me a real smile, please!”

Kim, who wore a black dress with matching leather corset to the dinner, even snapped a cute clip with her former pal, Chyna.

“Hey guys, it’s going down in San Diego tonight!” she says in the video before turning around and rubbing Chyna’s baby bump.

It has been several days since Rob deleted all of the photos from his Instagram without any explanation. Chyna has carried on without comment, snapping some videos of herself still wearing her giant diamond engagement ring.

Rob popped the question in April after a whirlwind romance between the pair. When he didn’t tell his family in advance, they weren’t pleased, which was documented on KUWTK, but they have seemingly since moved on.
