It looks as though they're one big happy family! The Kardashian-Jenner clan joined forces to ring in Khloé Kardashian’s 32nd birthday Monday night at Dave & Buster’s in Hollywood, California, and Rob Kardashian and his fiancé Blac Chyna were among the special guests.

The family, along with some of their closest friends like Chrissy Teigen and John Legend, donned their best casualwear to play games and take Jell-O shots for Koko’s big day. The reality stars took to Instagram and Snapchat to share photos from the fun night, and perhaps most surprising among them were photos of Chyna smiling with Kim Kardashian West and Kylie Jenner.

This isn’t the only way the Kardashian crew celebrated the momentous occasion: They flooded Instagram with adorable throwbacks in honor of Khloé’s 32nd, and momager Kris even posted a too-cute agreement that Koko had signed at 12 years old promising to never grow up.
