Kris Jenner did her best to keep her composure while stepping out for the first time since her younger sister Karen Houghton’s sudden death.

The momager put her mourning on hold to support her daughter Kylie Jenner’s latest business venture at an event in Los Angeles on Thursday night.

Kris, 68, maintained a neutral expression as she entered the launch party for Kylie’s new canned vodka soda brand, Sprinter, while wearing a white tuxedo with a black silk lapel layered over a ruffled button-down shirt.

The Kardashian-Jenner matriarch announced Tuesday that her only sibling had died at the age of 65.

“It is with the heaviest heart and deepest sadness that I share that my sister Karen passed away yesterday unexpectedly,” she captioned a slideshow of photos of Houghton over the years on Instagram.
