RadarOnline reports the matriarch of the Kardashian-Jenner brood has been "acting as the de facto marriage counselor and mediator between Lamar and Khloe," according to our family insider.
"Khloe kicked Lamar out of their home several weeks ago and he has been living in different hotels. Kris believes that Lamar has a lot of unresolved issues surrounding his childhood and he needs to work through it.
"She is encouraging Khloe NOT to give up on her marriage and not file for divorce."
The source added that Lamar, 33, has vowed to "never cheat on Khloe again."
"Khloe hasn't been able to forgive him yet, but a divorce likely won't happen," the insider added.
Worryingly for Odom and Kardashian, Polonsky passed a lie detector test!
At the weekend, the Kardashians and Jenners celebrated youngest sibling Kylie's 16th birthday with another party. Noticeably absent: Lamar.
"The family is absolutely livid at him for doing this to Khloe. Khloe is keeping a brave face in public and she is a tough cookie, but this has absolutely devastated her, obviously. She loves Lamar and wants to have a family with him, even after all of this," the source told Radar.
