She's easily the funniest K sister!

Khloe Kardashian guest hosted Chelsea Lately on Wednesday night, and the reality star didn't hold back with her raunchy jokes, specifically when she addressed rumors O.J. Simpson was her real father!

"I really hope that's not the case because I did f**k him once," she joked before adding, "I did f**k him one time - it's OK!"

The Keeping Up with the Kardashians star also took the opportunity to slam her sister Kim and momager Kris Jenner!

"My mom basically tags around with Kim, follows her around, dresses like Kim. It's like the Kim and Kris syndrome - they've started dressing alike," she told the audience.

We think Khlo should get her own show after seeing how well she did on this one!
