Former basketball star and soon-to-be ex-husband of Khloé Kardashian Lamar Odom has checked himself into rehab .
According to E! News, Odom hasn't relapsed but is instead trying to make a concerted effort to recover from his addictions.
"It was his own decision. He wanted to work on his mental and physical health for the next chapter of his life," a source told the news outlet.
This will mark Odom's second stint in rehab. Kardashian was able to persuade him into a three-week stay in August 2012.
Rumors had been flying about whether or not the former Lakers star had once again fallen off the wagon when he was reportedly seen drinking at bars over the Easter holiday. And as we reported, he became so intoxicated that he was removed from a plane after vomiting on himself in July. Yahoo reports that Odom's friends recently attempted to stage an intervention.
As of now, Odom has been in rehab for four days and is expected to complete an extended stay. E! News' source says, "It is not easy, but he is focused and determined."
