Khloe Kardashian poses with Kylie Jenner in Christmas pics

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 toPeople.

The images, posted to Khloe's Snapchat, are notably cropped just above the youngest Jenner's baby bump.

Sporting long tresses that contrasted with her previous bob and bangs, Jenner pouted for the camera alongside her half-sister.

She covered up her baby bump with a leather jacket and a crop top in the black and white shots.

'Kylie looked great but didn’t really draw any attention to her baby bump,' People's source said of the makeup maven. 

'She still acts like she wants to keep her pregnancy private.'

But on Christmas morning, she made a rare return to social media and was all smiles posing alongside her pregnant sister for a series of sweet snaps.

'Merry Christmas! People think you weren’t there last night,' Khloe said to Kylie before she responded, 'I was.'  

Also appearing in the candid snaps were "momager" Kris Jenner and model Kendall Jenner.

Kardashian family matriarch Kris wore a colorful floor length gown with a plunging neckline.  

Meanwhile Kendall bore a strong resemblance to her mom Kris as she wore an elegant white gown embellished with diamonds. 

Kim Kardashian, Kanye West and Kendall Jenner were in the holiday spirit as R&B icons Babyface, Toni Braxton and Brian McKnight provided the musical entertainment.

The boyfriends of Christmas past and present were in joyous spirits under the Calabasas sky, as Kourtney's ex Scott Disick was in attendance, as was her current beau, model Younes Bendjima.

Also seen at the luxe bash was songstress Christina Aguilera, and a number of prominent family and friends of the first family of reality television.
