Lamar Odom is worried that his messy, and very public, separation from Khloe Kardashian will be aired on season 9 of Keeping Up With the Kardashians and portray him in a bad light, a source said recently.

After four years of marriage, Kardashian filed for divorce from the NBA player on Dec. 13 citing "irreconcilable differences." The falling apart of their marriage and other elements of their relationship is set to be a storyline in the upcoming season of KUWTK, though the idea concerns Odom. 

"The last thing Lamar needs in his life is to be portrayed as a schmuck. Khloe has assured him that it won't be bad, but how can it not be?" a source told Radar Online. "The end of the marriage is going to be Khloe's main storyline next season and Lamar is afraid that his drug use and cheating will be addressed on the show."

The source added that bad press will hurt Odom's attempts at reviving his career, which he is still hopeful that he can do.

"He is trying to make a career comeback and he thinks this is going to hinder and hurt those efforts. He feels he's going to be used to get ratings for the Kardashians."

Based on the supertrailer for season 9, released last week, viewers already know that Kardashian's split with Odom -- as well as her family's reaction to it all -- will be shown on the E! series. Fans might see is a transition in the type of relationship Kardashian and Odom have. While they won't be husband and wife anymore, they may still remain close in another way.

"It's definitely a mother-son type of relationship. She is making sure he is taking care of responsibilities with his DUI and meeting with his trainer," the insider said. "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."

Despite previously saying she still loves him, the source added that Kardashian's mother, Kris Jenner, is "privately disgusted" with Odom's actions lately and could use it against him.
