On Friday Khloe Kardashian and sisters Kendall and Kylie Jenner went on a topless Hollywood tour, and the trio donned elaborate disguises that rendered them completely unrecognizable. With a wig and some jowls, Khloe morphed a 79-year-old grandmother from Albuquerque, New Mexico, who was visiting Los Angeles with her granddaughters, Kylie and Kendall. She joked that Kylie looked like the "old" Kylie Jenner. Lol, burn!

The ladies filmed the entire thing on their phones and posted it on Snapchat, but they nearly gave away their identities at one point on the tour. The guide mentioned how Tyga wouldn't let Paul McCartney in to his Grammys after-party, and Kylie started yelling in her obnoxious voice, "That's not true!" Guess they can't totally go incognito.

Kourtney Kardashian tweeted, "Omg!! I have never laughed so hard watching @khloekardashian on @KylieJenner snapchat. I'm literally crying. Khloe you are just it for me," while mom Kris Jenner added, "You guys have to see @kyliejenner's snapchat story today!!! #sofunny #mykidsarecrazy."

When asked about the Kardashians, Khloe yelled, "F*ck those ho's...The Kartrashians? I don't wanna talk about those Kartrashians." Watch the videos below!
