After Lord Disick tells Kourt he feels “like you love that you’re able to hold this over me and that’s like your control factor,” his baby momma hits back by saying:

“And I feel like you think you can go out and do whatever you want and purposely try to hurt me and still get invited to everything.”

The mother-of-three is of course referencing his crazy partying at Cannes earlier this year.
The back-and-forth was so intense, moderator Khlo├â┬⌐ said the entire thing was “fucking nuts.”
