What ACTUALLY happened when Khloé , Kylie, and Kendall went undercover on that Hollywood tour

Back in March, Khloé Kardashian, along with her younger sisters Kendall and Kyle Jenner, went undercover on a Hollywood tours ride — for what seemed like absolutely no reason at all other than having the best time ever (and, as it turns out, for TV).

Khloé played the role of a 79-year-old grandmother from Albuquerque, New Mexico who was visiting California with her two granddaughters — played by Kylie and Kendall. No one had a clue who they were, and it was hilarious. That is until Kylie started Snapchatting their adventure and fans caught on.

How did the Kardashian-Jenners manage to complete transform into different humans? Makeup and prosthetics, of course.

We’re now finally getting a deeper look at what exactly went on during their escapades. In a clip from this Sunday’s episode of Keeping Up With the Kardashians, we see Dolores “Dottie,” Sam and Natalie with their Southern-ish accents and modified faces, hair styles and even earlobes for their undercover adventure. And honestly, they look completely different.
