Lamar Odom and Khloe Kardashian

The hits just keep on coming for Khloe Kardashian and Lamar Odom.

The troubled couple was the subject of more speculation this weekend, after Odom allegedly went missing, and Kardashian was unable to get hold of him for 72 hours, TMZ.com reports.

However, Odom's agent, Jeff Schwartz, refuted the story on Monday. "Lamar is not missing. His wife knows exactly where he is," Schwartz told ESPN.com. "Playing in the NBA is still very much a part of Lamar's plans."

An unnamed source told ESPN.com that Odom is currently at a Los Angeles-area hotel, and his friends are trying to get him help for an "unspecified drug problem."

Kardashian reportedly threw her husband out of their house Wednesday after trying to stage an intervention, TMZ.com reported. An earlier TMZ report claimed that Odom had been battling an addiction to crack cocaine for more than two years, and that his drug use is "the principal cause of the crisis in his marriage to Khloe Kardashian."

Neither Odom nor Kardashian has officially commented on the reports; however, Kardashian tweeted Sunday afternoon: "Really hard to sit here and listen to people talk sh-- about my family! F--- you and shame on you! I'm too protective for this sh--!"

Although Kardashian had been photographed without her wedding ring last week, X17.com photographed the reality star on Monday with her ring.
