SnapchatBlac Chyna is already part of the family.
Rob Kardashian was noticeably M.I.A. at his grandma MJ Campbell's birthday bash Tuesday, but his pregnant fiancée joined the Kardashian family's celebration at The Marine Room. Kim Kardashian posed for a Snapchat video with her future sister-in-law, telling fans, "Hey, guys. It's going down in San Diego tonight." She then turned around and rubbed the model's baby bump. Scott Disick, Corey Gamble, Kris Jenner, Khloe Kardashian, Kourtney Kardashian and Kris Jenner joined the E! stars in celebrating MJ's birthday at the French seafood restaurant.
During the family dinner, Kim's 3-year-old daughter North West adorably refused to smile for a picture with her great-grandmother. "My two fave girls," Kim said on Snapchat. "Is that the kind of smile you're going to give me? Give me a real smile, please! You've been so naughty!" Kris tried coaxing her granddaughter into smiling for Kim, saying, "North, you're going to get cake!"
Earlier in the day, the family opened a Dash store. "It's my grandma's birthday. We're at our store opening," Kim, 35, said in a Snapchat video. Her mom, 60, added, "Congratulations, MJ!"
The family also shared well wishes for MJ via their social media accounts. "Happy Birthday to the most amazing grandma in the world! I love you so much words can't even explain!" Kim tweeted. Kris tweeted a photo collage and wrote, "Happy birthday to my mom!!! I love you more than words can possibly say!! Thank you for your endless, unconditional love + for being the most supportive, generous, kind + patient mother and the most stylish woman I will ever know! I am so blessed to have you. You're an inspiration to me and you are cherished by us all!!" Kourtney shared an old photo of MJ and Kris, tweeting, "Happy birthday to my beautiful grandmother who inspires me every day. You are the coolest, strongest woman I know."
It's unclear why Rob missed MJ's birthday party, but it's been several days since he deleted every picture from his Instagram account without providing any explanation. (Of course, it's not the first time Rob has done such a thing.) Chyna has not publicly commented on her fiancé's latest social media purge, but as a source told E! News Tuesday, the couple had "been getting into little tiffs" and Chyna "flipped" on Rob over the weekend. "He was so pissed at how she spoke to him, so he deleted everything about her to hurt her." The source added that Rob "has never cheated on her, but she is very paranoid about that from past experiences." The parents-to-be have since moved past their argument. "[They're] back in love," the source said.
Meanwhile, Chyna is only getting closer to Rob's family. "They have talked to me about names, but I would never tell because that's really personal to them. If they want to share that, they could," Kim told E! News last week. "But we're just there to support them. We're so excited that we're getting a new cousin." The mom of two added that she's excited to see Rob become a first-time father. "I think they're just starting to get into it, but we share a ton of different baby stuff. I think once it starts happening for them we'll have way more tips, once the baby's here. I'm excited to see my brother in this role as a dad. I think he'll be an amazing dad."
