EXCLUSIVE: Kendall and Kylie Jenner reunite for rare selfie

They haven't posted a picture together in months but Kendall and Kylie Jenner certainly seemed to make up for lost time last night.

The two sisters enjoyed a rare girls' night out when they went to a Christmas party hosted by Kardashian-Jenner family friend Shelli Azoff.

Pulling the mother of all pouts, the girls sat down at their table and posed for some moody selfies, which they posted on their separate Instagram accounts.

Model Kendall, 24, appeared to be wearing a strapless floral dress that showed off her cleavage as she leaned in for the photos with her younger sister.
