Blac Chyna and Scott Disick surprised fans by attending Khloe Kardashian's 32nd birthday party on Monday.
Blac Chyna was all smiles as she posed for photos with Khloe, Rob and their family at Dave & Buster's in Los Angeles.
The bride-to-be even posted a picture with Rob's mom, Kris Jenner, with the caption, "So much fun with Mama."
Disick, meanwhile, snapped a photo with Rob and three of the star's friends. Kris shared the picture on Instagram, writing, "One of the best nights ever ever... This made me so happy. Epic moment last night with Rob and his best friends."
Khloe and Rob's half-sister Kylie Jenner, who is dating Blac Chyna's ex-fiance, Tyga, was also present at the event.Kim Kardashian had denied rumors of family drama with Blac Chyna and Rob in the July issue of GQ magazine.
"We're all on board," the "Keeping Up with the Kardashians" star said of the match. "We definitely see that my brother is happy and getting healthy, and whatever gets him to that place, you know, we're happy for him."
Disick and Kourtney, who share three children, split in July 2015 after nine years of dating.
Kourtney said in April she is open to a reconciliation with Disick, although sources told People this week the club promoter is dating other women.
