Kim and Khloé Kardashian Get Down and Dirty

After getting upstaged by her sister in the sexiness department, Kim Kardashian decided to take her sibling, Khloé Kardashian, on a mud run. The pair, along with a female friend, donned black workout clothes and pink bandanas as they ran the obstacle course, which included a giant yellow slide that landed participants in a huge pile of mud. Kim clearly isn't taking it too easy as she prepares for her upcoming nuptials to Kanye West. The pair are set to wed in May near Paris. Source: Instagram user khloekardashian
