It seems like everyone is doing the Y2K thing these days, as it was a good era to be in, pretty much. Kendall Jenner and Hailey Bieber are revisiting this historic time period by dressing up as Paris Hilton and Nicole Richie-two of the It Girls from Y2K-and the stars of The Simple Life for Halloween.

Kendall and Hailey nailed Paris's and Nicole's The Simple Life promotional looks by going as authentic as possible and embodying the spirit. It's also Halloween, so the passion's strong. What other time (other than conventions) to impersonate your favorite icons or idols?

Kendall and Hailey went with season 1 of The Simple Life for their collaborative costume ideas. In the photo that Hailey posted in her Instagram Stories, then reuploaded by a fan page, Kendall gets into character as Paris in her two-piece denim laced-up top and miniskirt. She's even holding a cute Yorkie pup in the replicate way Paris held her chihuahua, Tinkerbell. Hailey, for her part, nipped into Nicole with denim overalls and a pink and green embellished bra that exposes part of her midriff. She completes the ensemble with a pearl charm necklace and pitchfork. The two supermodels stand in front of a red barn and farmland, where the first season took place.

Paris and Nicole loved the looks Kendall and Hailey pieced together after watching the latter's now-viral video on TikTok. The clip contained one of Nicole's most memorable scenes, with Hailey mouthing the words (and profanity) to perfection.

"Icons recognizing icons!" Paris says in the TikTok comments. "Obsessed with this!"

"I am obsessed!" Nicole says after she reposted the IG Story from Hailey.

Speaking of which, Paris and Nicole will return to TV with their The Simple Life reboot in December. Only a tiny bit has been revealed about the show's narrative, and it'll be at an opera audition, with the two BFFs as directors.

What other costumes and disguises will the Kardashian-Jenners unveil? We can't wait to see!
