According to a report by TMZ, Khloe Kardashian's four year marriage to Lamar Odom is over as she's set to file for divorce today.

Sources tell us, Khloe will be citing irreconcilable differences in her legal docs. The split should be pretty cut and dry -- an ironclad prenup which kept all their assets separate ... and no kids.

As we reported, Lamar's bizarre freestyle rap video -- in which he brags about cheating on Khloe -- was the last straw in their crumbling relationship.  Immediately after TMZ posted the video last month, Khloe stopped wearing her wedding ring.
