"Khloé, I just want to know," Kim corners her sister. "Why are you lying to me about this supposed boyfriend?"
"That's ridiculous!" Khloé exclaims, stunned by Kim's remark.
"It's kind of annoying that I have to find out all this information on the Internet instead of straight from Khloé," Kim reveals to the camera. "If anything, my sisters are the first people I tell all my business to, so it's kind of weird that Khloé can be so secretive."
"Like seriously, you lead a double life," Kim states. "You go away at night and you have a whole new set of friends! Who are your friends?"
Watch the clip above to see Khloé open up on her past life and tune-in on Sunday's to see what happens when Kim finally meets Khloé's new man!
