Kim Kardashian West takes her Christmas décor very seriously.

In a sneak peek at Sunday’s special holiday episode of Keeping Up With the Kardashians, Kim stops by a holiday prop shop with sister Kourtney Kardashian and momager Kris Jenner — and tensions are running high from the get-go.

“If anyone copies me on this situation here …” begins Kim, 37, pointing to a display of twinkly lights.

“What?! I already tagged those,” insists Jenner, 61.

“I already bought them all last week when I was here,” says Kourtney, 38.

In a confessional, Kim explains that she’s laying down the law since she and Kourtney got into “the most epic fight” last year after her sister “fully copied” her light display. (“This makes me not want to have a big family,” snapped Kim in a KUWTK flashback. “Because no one is f—ing original.”)

“I have warned everyone,” she says. “I will come for them if they even dare try to copy anything that I’m doing this holiday season.”

As Jenner sneakily trails after her daughter in the store, Kim picks out everything from wrapping paper to golden angels.

“See, this is the kind of Christmas tree that I want,” Kim says. “I want like, a real bark tree. But I won’t tell all my ideas out loud — my mom is somewhere, lurking.”

Jenner then turns to Kourtney to ask what kind of “vibe” she’s going for this year, but Kim is quick to interrupt.

“Why don’t we not talk about our vibes?” she says. “That way no one can like, steal a vibe?”
