The on-again, off-again couple was spotted on a dinner date Wednesday night at TAO restaurant in Los Angeles, CA, about two months after news circulated they had split, Us Weekly reported.
Kardashian, 30, and Chyna, 28, reportedly posted flirty Snapchats of their night out together in Hollywood.
Kardashian wore a green sweatshirt, L.A. Dodgers baseball hat and grey pants, while Chyna rocked long lavender locks, a jean jacket over a white shirt, tight white pants and sneakers.
In one video Chyna shared, she rested her hand on top of Kardashian's hand when placed on her thigh.
While such a picture has sparked rumors of a reconciliation, Chyna was noticeably not wearing her 7-carat diamond engagement ring that Kardashian proposed with in April 2016, according to Us.
Kardashian reportedly posted another Snapchat video in which he was poking fun at Chyna's hair, joking that it "looks ugly" -- a comment which prompted the mother of his child to flip off the camera.
The former Rob & Chyna stars welcomed their five-month-old daughter Dream Renee in November 2016.
Chyna told Cosmopolitan South Africa in March that she and Kardashian have been attending therapy and trying to work things out.
"I'm in it for the long haul, so I feel like my advice [for anyone in a similar situation] is therapy, know each other's family, calling each other's moms," Chyna said.
"I know we love each other and we're fighting for each other, and the people we surround ourselves with are rooting for us."
An insider close to the couple recently told People that most of Chyna and the sock designer's problems stem from the longtime Keeping Up with the Kardashians star's insecurities due to his weight, health and career.

As shown on Rob & Chyna, both individuals also have bad tempers and struggled to trust each other.
"Chyna is super fed up with Rob and thinks he is way too emotional and depressed," noted the insider. "She thinks he has terrible issues."
