A few days after reporting that Lamar Odom is battling a "hard-core drug abuse problem," TMZ is reporting that Odom has been missing for 72 hours.

According to the report, Odom went missing shortly after an intervention attempt by wife Khloe Kardashia

n on Wednesday evening. The former Lakers star was allegedly thrown out of the house after refusing to participate in the intervention.

As of Sunday, his whereabouts are unknown.

No family members on either side have been able to get into contact with Odom since that night, and fear that he is in the midst of a drug binge, TMZ alleges.
