Kim and Khloe Kardashian once got down and dirty in the mud together.
In a 2014 episode of Keeping Up With the Kardashians, the Kardashian sisters decided to compete in a mud run, and things got very messy!
Both Kim and Khloé were feeling very competitive during the run. There was pushing, shoving and trash talking.
At one point, Khloé even grabs Kim and throws her down in the mud!
See the sisters roll around in the mud in the throwback clip!
