And no, we're not talking about a beauty treatment although this certainly is a new look for these lovely Kardashian ladies!
Kim and Khloe Kardashian partook in the annual Mud Run on Saturday morning and shared pictures of the two enjoying their time on Instagram!
The Kardashian sisters were definitely not afraid to get down and dirty as they slid down a slippery slide into a giant pool of muddy water!
KoKo documented parts of the race with her big sissy, she captioned the photo (above):
