The 'Keeping up with the Kardashians' star filed for divorce from the troubled sportsman - who was accused of cheating on her and being addicted to cocaine - earlier this month but is still giving him her support as he tries to stay sober.
However, friends of the former couple - who were married for four years - insist they have no plans to get back together.
One insider told RadarOnline.com: ''Khloe has been in constant contact with Lamar daily since filing for divorce ... she is making sure he is taking care of responsibilities with his DUI, and meeting with his trainer.
''It's definitely a mother-son type of relationship. There will always be a lot of love there between the two, but Khloe has definitely moved on.
''There are zero plans for the former couple to reconcile, and both are very amicable right now, which is a good sign for the divorce. It should be quick, and no drama.''
Lamar - who recently agreed to plead no contest in a driving under the influence (DUI) charge and was put on probation for three years and rdered to attend an alcohol education class - is ''thankful'' for Khloe's friendship.
The source said: ''Lamar appreciates having Khloe in his life....he is thankful to her for making sure he is taking care of business obligations, and meeting deadlines. The two will always be friends.''
