Several of Lamar Odom's teammates reportedly staged an intervention with the NBA star on Monday afternoon at a Los Angeles hotel room, but Odom refused to listen to them and apparently left. His whereabouts are currently unknown.

The dramatic talk lasted three hours, and according to Radar Online, Odom's agent, Jeff Schwartz, was also present at the intervention. The site reports that Schwartz made a series of calls and "begged him to return to the hotel," but Odom didn't come back.

An insider reveals that Odom, 33, "appeared to be under the influence of a substance," telling the site, “Lamar was sweaty and talking very fast. His hands were shaking and he couldn’t sit still. He kept pacing in the room."

“There was a bit of time it appeared that Lamar was going to admit publicly his addition and go to rehab, again,” the source continued. “But then, he abruptly bolted from the hotel and left the premises ... One minute Lamar is agreeing that he needs help and 30 minutes later, he says he just needs to be left alone. This is extremely serious, but there is really nothing anyone can do to save Lamar unless he wants to save himself.”

Khloe has been visiting Lamar since they separated, and though she took her wedding ring off last week, just yesterday X17 snapped these exclusive photos of the starlet with her diamond wedding band and engagement ring back on. Maybe if she has another meeting with him they couple might be able to make some progress?

Radar reports that Lamar is suffering from an addiction to OxyContin and Ambien, but TMZ claims that the baller is using crack cocaine. Either way, we hope Lamar gets the help he needs.

We reached out to Schwartz, but he has yet to reply to our our request for a comment.
