Just a day after her parents filed for divorce, the 18-year-old fashion model posted an Instagram of her mom and dad in their happier (and younger) days.
In the picture, captioned only with a heart emoticon, a fully feathered Bruce wears a tux and colorfully matching bow tie, cummerbund and pocket square with his arm tenderly around a glamorous Kris, who is showing some skin and sporting a leopard-y necklace.
The Kardashian matriarch, 58, and former Olympic gold medalist, 64, officially filed for divorce Monday, 11 months after announcing their separation.
They married in 1991 and have two daughters, Kendall and Kylie, 17.
Despite the family upheaval, Kendall has had a hugely successful September, walking the runway during New York Fashion Week for Tommy Hilfiger, Diane von Furstenberg, Donna Karan and Marc Jacobs and taking Milan Fashion Week by storm.
