The reality star just kicked off her new series Revenge Body where contestants work with Koko and a team of professionals to reach their weight loss goals.
In one of the eps we are introduced to a guy named Joel who joins the series in order to get back at his ex BF who he claims has leukemia.
The trainers are put off by Joel after he shows up late, doesn't take the workouts seriously and continuously pretends to cry.
One day, Joel calls Khloe to tell her that his ex had just passed away and Khloe encourages him to press on with the program.
Joel later calls Khloe to tell her that he had lied about the whole thing with his ex which srsly angers the reality star and she decides to fire him from the show.
"I don't know what's true or not anymore. I just don't think this journey is for you and I just kind of think this is the end of the road for us," Khloe told Joel.
Khloe then took to Twitter to slam the former contestant for lying to her and her team.
"So disrespectful!! Joel totally played us... and we have no time for fakers!! #RevengeBody."
Don't mess with Khloe!
