Lamar Odom reportedly is not in rehab despite prior reports claiming otherwise.

The NBA basketball player and husband of Khloe Kardashian is not in rehab although People and Us Weekly, among others, reported yesterday he had checked himself into a drug and alcohol facility to address his substance abuse issues, according to TMZ.

TMZ insiders are claiming Odom is not currently seeking treatment -- which would help explain the website's report earlier today that Kardashian had no idea Odom entered rehab to begin with. 

Kardashian was reportedly "blindsided" by the news Odom had checked himself into rehab, as the couple has not spoken to one another in recent days. 

Odom -- who has spent the last couple of weeks at the center of numerous headlines alleging he has a hardcore drug problem which has put strain on his marriage to Kardashian -- was arrested on suspicion of driving under the influence last Friday morning, according to People.

After reportedly being taken into custody, Odom was taken to a jail in Van Nuys, CA before he was released on $15,000 bail, according to the Los Angeles County Sheriff's Department.

Reports that Odom struggles with a serious two-year drug problem that has since jeopardized his professional basketball career and gotten him temporarily kicked out of the home he shares with Kardashian first surfaced late last month and followed prior reports that he's repeatedly cheated on his wife, leaving her on the verge of filing for divorce.
