Kardashians Bust Out Baby Footage For Holiday Special: Watch The Preview

'The Kardashians: A Very Merry Christmas' is slated to air December 1 on E!.

Get ready. "It's that time of year!" Kourtney Kardashian declares in the teaser for the upcoming "Keeping Up with the Kardashians" Christmas special.

"The Kardashians: A Very Merry Christmas" is slated to air on December 1 on E!. It will not only feature appearances from the family, but also never-before-seen home videos of the kooky crew. All the big players are in the promo, wearing black and white PJs — except Kim's fiancé Kanye West, their daughter, North, and Khloe's estranged husband Lamar Odom.

Of course, Scott Disick is his usual sarcastic self. When footage of girlfriend Kourtney as a kid with a bowl haircut flashes on the screen, he says, "It looks like a Portobello mushroom."

The special will also include the big reveal of this year's Kardashian's Christmas card. The one-off episode comes just weeks after last Sunday's season finale of "Keeping Up With The Kardashians."

The family shot the special back in September. At the time, Kim tweeted about hitting the set.

"Long beautiful work day with the family! Shot a very fun Christmas special! Can't wait to share more later! Night! Xo," she wrote, also giving fans a first look at the holiday special, which marked one of her first times back at work since giving birth to North back in June.

Earlier this year, Khloe opened up to MTV about why fans want to keep tuning into seeing whatever it is the Kardashians are up to.

"Honestly I feel like I'm constantly [learning stuff about us]. As we get older, we all learn new things about ourselves and we grow and we, I don't know, we just evolve as people. Every season we're like 'What else is there for us to film? Like how do people still want to watch this 'cause haven't we done everything?' And then someone gets knocked up or someone's having this or whatever," she said back in June. "And there's always more 'cause that's life — everything changes and happens."
