You NEED to see Khloe, Kendall and Kylie acting as tourists in disguise

So Kendall and Kylie Jenner were having a blast with their big sis Khloe yesterday as the trio went undercover to go on a tour of Hollywood. 

And the disguises were rather impressive. 

Khloe donned grey hair and turned into an very vocal lady from Albuquerque while Kendall opted for a ginger wig. 

Kylie pretty much looked like herself except added a fake nose and fringe. 

And they seemed to be having a blast as they travelled around their own neighbourhood incognito. 

They even called out the tour guide when they got facts about the Kardashians totally wrong. 

The adventure was all documented on Kylie's Snapchat but it wasn't long until the paps caught up to them.
