The 28-year-old star was seen having a meal in West Hollywood, California, even though she did her best to keep a low profile.
The man joining her was definitely not fiance Rob Kardashian and comes just days after the model was reportedly getting cozy with a man during a Super Bowl party.
Chyna's lunch date was also at that party and photographed leaving with her on Sunday though it is not clear if he was the man she was seated with during the game.
On Friday, the pair sat opposite each other inside the upscale Japanese eatery and chatted away.
As she ate, the mother of two showed off her naked ring finger where her $325,000 seven-carat diamond ring from Rob used to be located.
