Khloe Kardashian and Kris Jenner can't keep up with one another's outfit choices.

The mother-daughter duo had an unintentional twinning moment at a holiday party at Casa Vega in Los Angeles Dec. 19, with both of them arriving in the same ensemble.

To commemorate the occasion, Khloe, 40, and Kris, 69, recreated an iconic Keeping Up With the Kardashians moment in which Kourtney Kardashian admonished Kris for copying her look.

"It's just not cool that you copy me," Kourtney says in the voiceover that Khloe lip-synced to. "I go to lengths to try to get things that not everybody has."

Both women rocked the tailored mini-dress from Kylie Jenner's clothing brand Khy with matching thigh-high boots, but in different colors—Kris opted for a white version of the long-sleeved piece, while Khloe rocked it in black. 

"We didn’t plan this," the Revenge Body alum captioned the Dec. 20 Instagram clip. "We just showed up at the same holiday party like this."

Also at the party—which was stocked with Kendall Jenner's 818 Tequila and Kylie's canned Sprinter cocktails—was Kim Kardashian, who donned a plunging red leather dress as she scootered around as she continued to recover from her broken foot.

Khloe posted a video of the Skims founder rolling through the restaurant cheekily set to El Loco's hit, "Low Rider," which contains the lyrics, "Low rider drives a little slower."

The Kardashians stars had already been in the holiday spirit, with Kris recently revealing how she keeps up with what all 13 of her grandchildren want from Santa.

"We have this family chat going around," the matriarch told E! News earlier this month, explaining that her kids will let her know what each of their little ones wants for Christmas. "It's really fun. Some of the things that they ask for are really cute."

"They're growing up," the Safely founder added. "They're loving new things. One year, they'll be into a certain type of doll. And then, you clearly see that shift when it's the following Christmas."

While planning is underway for Christmas morning, Kim recently revealed that the family is forgoing their usual Christmas Eve blowout party in lieu of a more intimate family gathering this year.

"Just because we have a lot of construction going on, so we're doing a really family intimate one that I'm really excited about," the 44-year-old told Vogue Dec. 12, before adding that her family will "still [be] dressing up to the nines, because that's what we do."

And fans of the family who love getting a peek into their annual Christmas party shouldn't fret, as Kim insisted that the festivities will resume in years to come now that the next generation is getting more involved.

"They're just beginning," she explained. "Our kids love them and now all their friends want to come. It's such a fun tradition."

Kylie Jenner's daughter Stormi Webster, 6, got hands-on as she helped decorate the Christmas tree.

Kylie gave her followers a closer look at her ornaments, which included popcorn, snowmen and mini Santas.

With the lights strung and the decorations hung, Stormi cracked a smile in front of the completed tree.

And Stormi chose to make her own personal Christmas tree a bubble gum pink shade. 

Kylie's son Aire Webster decked out his own tree with motorcycle and train ornaments.  

Kourtney Kardashian's vibe right now is just living life—in the comfort of festive PJs and Santa-themed slippers.

One way Kourtney really made her Christmas decor stand out? An inverted tree, of course.

Kourtney also leaned into the seasonal color with a monochromatic theme.

What's better than one Christmas tree? Judging by Kourtney's foyer, a minimum of four.
