Lamar Odom Checks Into Rehab But Leaves Khloe Kardashian In The Dark

Lamar Odom has finally checked into rehab to deal with his raging drug addiction but Khloe Kardashian is totally unaware despite the fact she lead the campaign for him to get help in the first place.

According to TMZ; Sources close to the couple tell us Khloe never got so much as a heads-up about Lamar's plans, and was completely blindsided by the report he's checked in for treatment.

We're told one big reason for that is Khloe and Lamar have not been talking at all since she issued an ultimatum last weekend -- get help or our marriage is over -- intending to force his hand on the issue of rehab.

As we previously reported ... Lamar started a treatment program last summer in San Diego, but bailed after only 3 weeks.

One source says although Khloe's been kept outside the loop this time -- she does hope wherever Lamar is ... he's actually getting professional help.
