They’re rumored to be expecting around the same time in 2018.
And moms-to-be Khloe Kardashian, 33, and Kylie Jenner, 20, posed together in a photo booth at Kris Jenner’s Christmas Eve party on Sunday, after Jenner had earlier been ‘celebrating away from cameras’ at her “momager’s” annual event, according to People.
The images, posted to Khloe’s Snapchat, are notably cropped just above the youngest Jenner’s baby bump.
