The 37-year-old reality star hit the town with a gal pal, mom Kris Jenner and her mother's boyfriend, Corey Gamble.
Kourtney Kardashian stepped out in what might be the littlest black dress of all time.
The mother of three showed up to West Hollywood hot spot, Delilah, wearing a mini-dress and sky-high heels, and was joined by gal pal Stephanie Shepherd, mom Kris Jenner and her mother's boyfriend, Corey Gamble. Kourtney later hung out with makeup artist Joyce Bonelli, and hit up a house party with rapper French Montana.
Kourtney's Sunday night out on the town marked the second time this weekend she was spotted in a skimpy black dress. The 37-year-old reality star also turned heads at Clive Davis' Pre-GRAMMY Gala on Saturday night when she posed on the red carpet with Kris wearing a sheer black cut-out dress.
