Lamar Odom's friends and family members reportedly haven't been able to contact the basketball star for almost three days and are concerned he has gone a crack cocaine-fueled drug binge, according to TMZ. Khloe Kardashian threw Odom out of their house on Wednesday after he rejected pleas that he get sober. Odom, who has been battling his drug addiction, agreed to go to rehab in San Diego last year, but left after only three weeks of treatment. Odom has been having difficulty since the basketball season ended and he became a free agent. A rep for Odom says he's alive and well, but would not give any information about his whereabouts.
