The Keeping Up With The Kardashians star, 59, dressed in all black for her evening at Craig's restaurant in Los Angeles on Tuesday (9 June).
Kris and Corey, 33, are believed to have met last summer while attending a mutual friend's birthday in Ibiza.
He's been featured on the family reality show, memorably in a segment where Kris' daughter Kim complained her mum was having sex too loudly in the next door bedroom!
Kris' happy date night came after her ex-partner, Caitlyn Jenner, revealed her new persona in Vanity Fair magazine. They were married for 22 years and have two children together: Kendall, 19, and Kylie, 17.
Meanwhile, in an interview this week, teenager Kylie claimed Kris had cut her off financially at the tender age of 14!
Kylie told InStyle: "My mum cut me off financially three years ago so I pay for everything – my car, my gas and food, as well as my clothes."
