Khloe, 29, is said to be having a tough time saving her marriage with Odom, 33, after the athlete was accused of allegedly using drugs and cheating on his wife, reported Hollywood Life.
"Kris is desperate for Khloe to divorce Lamar. She thinks he is bad news and that Khloe can do much better. Another reason Kris wants Khloe to dump Lamar is because he has absolutely nothing to offer her or the family," a source said.
"He isn't officially signed with any team. He won't go to rehab, and he is a bad influence on Rob [Kardashian]. Kris thinks that Lamar has tarnished the family name with philandering and drug use," the source added.
