Despite frequent disagreements with his famous family, Rob Kardashian reunited with the Kardasian-Jenners on Thursday to celebrate his 29^th birthday.

Rob, whose birthday falls on March 17^th, joined his family for a belated birthday dinner at Japanese restaurant Nobu in Malibu, California. The entire clan was present, including mom, Kris Jenner and sisters Kourtney and Kim Kardashian as well as Kendall and Kylie Jenner. Kourtney took her children, Mason and Penelope Disick to the party, and Kim brought daughter, North West as well.

The family’s significant others were also in attendance – Kris Jenner’s boyfriend, Corey Gamble; Kim Kardashian’s husband, Kanye West; and even Kourtney’s ex-partner, Scott Disick.

Noticeably absent, though, was Khloe Kardashian, who later tweeted that she was “too ill” to attend the birthday dinner. Caitlyn Jenner also did not take part in the festivities, but it was the absence of Rob’s girlfriend, Blac Chyna that raised some eyebrows.

Rob Kardashian and Blac Chyna’s recent romance immediately earned his family’s disapproval, mostly because the model-entrepreneur was formerly engaged to Kylie Jenner’s boyfriend, Tyga, with whom she also shares a three-and-a-half-year-old son, King Cairo. To complicate the drama even further, Blac Chyna is close friends with Kanye West’s ex-girlfriend, Amber Rose.

Kourtney Kardashian posted a rare photo with Rob Kardashian looking quite happy to spend time with his family. Kim also posted adorable shots of the kids having a great time at the restaurant, as well as a brief Snapchat featuring the men of the family.

To cap off the special occasion, a custom birthday cake was brought out – one that had a throwback photo of young Rob’s smiling face.

While Blac Chyna was excluded from the family party, she did get a chance to celebrate her man’s birthday with him. She and Rob Kardashian headed over to Legoland California with her son, after which they had burgers at In n Out.
