The on-again couple split earlier this year, but continue to co-parent their daughter, Dream. Earlier this month, they were spotted getting cozy on Snapchat
, as Chyna danced around Rob and even got a kiss on the cheek from him.
They also enjoyed time with Dream
together earlier this week.
But Rob was nowhere to be seen while Chyna had her night out, which ended with her getting into a white car with a male friend.
Other stars at TAO on Tuesday included Drake and Kardashian pal French Montana, who hung out with Chyna on Instagram several months ago.
