Lamar Odom is worried his alleged drug use and infidelities will be addressed on the new series of Keeping Up with the Kardashians.

The basketball player was left heartbroken after his wife Khloe Kardashian filed for divorce last month, and he's now concerned he will be portrayed in a negative light on her reality TV show as the break-down of their marriage will feature heavily on the program.

"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? 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. At the same time, 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," a source said.

Khloe called time on their four-year marriage after allegations came to light early last year that her troubled beau had cheated on her with multiple women and had also been battling a crack cocaine addiction.

However, it was revealed two weeks ago that the 30-year-old reality star is still in contact with 34-year-old 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 ordered to attend an alcohol education class - and is determined to help him stay sober.

Friends of the former couple insist they have no plans to reconcile.

The new series of Keeping Up with the Kardashians will air on January 19.
