Khloe Kardashian is reportedly set to file for divorce from estranged husband Lamar Odom very soon.

TMZ claims Kardashian will file for divorce as early as Friday (Dec. 13) and will allegedly cite irreconcilable differences as the reason. The two have a prenuptial agreement in place.

The website reports that Odom's bizarre freestyle rap video, which first surfaced last month, was "the last straw" for the reality star, who's been reportedly struggling with the relationship for months. In the rap, he supposedly says: "And when Khloe's out of town / I still be on the DL."

Kardashian and Odom married in 2009 after just one month together. Last August, reports came out about Odom's alleged drug abuse after he supposedly went missing for days. Since then, the couple has been seemingly estranged, except for a meet-up at Kanye West's concert in October.

"She flip-flopped several times, but she can't imagine having kids with someone who refuses to seek help for his disease," a source told Us Weekly about Kardashian divorcing.

Odom has reportedly refused to go to rehab despite Kardashian's alleged insistence, according to RadarOnline.com.

"After she saw the video, Khloe demanded Lamar go to rehab … but he refused," a source told Radar. "Lamar admitted being under the influence when the video was shot, but insisted to his wife that he was once again sober. Sadly, now, Khloe has decided that she is done with all of Lamar’s lies and manipulation."
