“Khloe arranged for the guys to meet at her home a few weeks ago, because she wants to stay on good terms with Lamar and thought he and Tristan would keep things civilized,” said an insider.

“She didn’t count on how snarky and hostile Lamar was going to be, plus how super-protective Tristan acted in return,” said the insider.

“Lamar’s friends had to pull them off each other once things got really bad. Khloe now realizes they can’t be in the same room ever again.”
