A LOT will have changed by the time the Keeping Up With the Kardashians Christmas special airs and most of it will have to do with Kim's surrogate and Khloe's and Kylie's pregnancies!

We were on bump watch Sunday as the entire Kardashian-Jenner clan met up at mom Kris' house for a backyard ice skating event in the middle of 100-degree temperatures. The girls' dressed the part, Kylie wearing an oversized sweatshirt dress and Khloe a figure-hugging sweater dress for the early Christmas party. We barely got a glimpse of Kylie, as she spent most of the afternoon cooling off in the shade of Kris' huge lanai -- the same for Khloe, who while less protective about hiding her bump, definitely didn't done ice skates and hit the rink. She did cheer on Kim and Nori from the sidelines, though.

Kim and daughter North, pregnant Khloe, and Kris Jenner transformed the momager's back yard into a winter wonderland equipped with an ice skating rink to film an upcoming episode of Keeping Up with the Kardashians over the weekend, and Santa was on hand even though we still have two months until the actual holiday!

The Revenge Body star and sister Kylie have yet to officially announce their pregnancies, but Scott Disick sort of let the cat of the bag by discussing it at a recent appearance when asked if he'd give Khloe some parenting advice.

"If she ever asks, I'm sure I would try. But I feel like all of us are so close that all of our children are kind of brought up in the same vicinity, or one block over, that everybody's kind of there for each other. I don't really need to give advice per se because we are right there. It's not like long-distance, ‘Hey, maybe you should try this?' Everybody’s so hands-on that I feel like it will happen within time. So no real advice in that sense," he said to E! News.

Perhaps the family is trying to get a lot of their filming out of the way before Khloe and Kylie get too big and tired for long days on set?
