The Keeping Up with the Kardashians alum, 42, enjoyed a night out with boyfriend Travis Barker on Friday as they went to a party for PrettyLittleThing in West Hollywood.
She showed some skin in a black satin mini dress, featuring a cutout over her waist, which she accessorized with a pair of bejeweled fangs.
The couple was previously friends and they bonded over parenthood and their mutual love for their children.
Kardashian and Disick, who is dating 20-year-old Amelia Hamlin, recently commented on each other’s relationships in the KUWTK reunion special.
