Kylie Jenner poses on Snapchat with momager Kris Jenner

Kylie Jenner is rumored to be pregnant at 20, with the father being her 25-year-old boyfriend Travis Scott.

And when she posed on her Snapchat Story on Sunday, the cosmetics mogul kept her midsection discreetly out of frame.

The Life Of Kylie reality star - who was joined in the photo by her mother Kris Jenner - had draped her figure in a flowing black top.

Meanwhile, the 61-year-old matriarch of the Kardashian-Jenner family was wearing a black sweater with strips of gleaming fabric over her visible shoulder.

Mother and daughter both sported cartoon dog ears and snouts, courtesy a filter.

Before that, Kylie had spent a bit of time filming herself as she sat listening to music in her Rolls-Royce, which appeared not to be moving.

The Life Of Kylie star veered the camera this way and that, pouting.

A cartoon string of streamers was draped across the frame near the bottom, just above festive yellow text blaring that it was 'SUNDAY.'

Kylie had showed off her car - which is silver on the outside, with a black and blue interior - on Snapchat shortly beforehand.

Its door was open as it stood parked on a stone-tiled driveway. 

Meanwhile, Kendall Jenner was in the spirit of the Halloween season on Sunday, ready to play dress-up and posting the result to Instagram.

The 21-year-old looked en route to Studio 54 in the late 1970s, wearing a sparkling pair of cat-eye sunglasses and matching long gloves. 

Her neckline fell to her midriff, and she tucked her cleavage-baring white top into a high-waisted pair of royal purple shorts.

Kendall had got herself a blazer in the same shade of purple as her shorts, flinging it casually over one shoulder and holding it in place with her fingers.

She rounded off the look with a glistening pair of drop earrings, plus a black-and-white striped hat with an asymmetric brim.

In the brief video she posted to Instagram, Kendall modeled the outfit and twirled about, giving the camera a scarlet-lipsticked smile.
