Khloe Kardashian Odom - Khloe Kardashian unaware of Lamar Odom's whereabouts

Khloe Kardashian Odom doesn't know where her husband Lamar Odom is.

The 29-year-old reality TV star is said to be ''exhausted'' by the recent troubles plaguing her basketball player spouse, who reportedly quit rehab after just one day on Thursday (05.09.13).

A source told the UsMagazine.com: ''Khloe doesn't know where Lamar is. She's just exhausted. I don't think anyone knows where he is at this point.''

Lamar, 33, is thought to have entered an unspecified treatment facility to combat his alleged addiction to drugs and alcohol on Wednesday (04.09.13), but checked out just 24 hours later and Khloe is unaware of his whereabouts.

The brunette beauty's relationship with Lamar has been on rocky ground in recent weeks amid rumours of his drug abuse and several allegations of infidelity.

According to a source close to the star, Khloe ''cut him off'' following a heated argument a week ago, and told him to ''go get help''.

There have been conflicting reports about whether Lamar entered rehab to battle his demons, but Khloe is apparently unconvinced her husband sought treatment.

The insider added: ''She's not fazed by these reports. She doesn't believe it, she doesn't think he went to rehab. Khloe is so exhausted by everything. She doesn't know what's going on.''
