Is Khloe & Lamar's marriage on the rocks? According to TMZ, Khloe threw him out of the house this past Wednesday after Lamar flat out rejected an attempted intervention over his alleged addiction to crack cocaine, which was recently revealed to be the reason his marriage to Khloe has fallen apart.

Sources say that Lamar Odom has been battling an addiction to crack cocaine for a minimum of two years and things have gotten even worse since he became a free agent at the end of the basketball season. He supposedly checked into a rehab facility a year ago, but only stayed for three weeks.

Recent reports have also claimed that Khloe is convinced that Odom has cheated on her, but her main concern is the drug use.

Khloe is more concerned about saving Lamar than ending her marriage.

Pretty disappointing being that Khloe and Lamar seemed to be the closest thing to "reality" when it came to the Kardashians. We hope things aren't as bad as they seem.

We'll keep you posted.
