Khloe Kardashian and Lamar Odom's marriage is on the rocks, and it looks like more than just idle gossip about Jennifer Richardson and Polina Polonsky.
Reports say he has a serious drug problem.
The 33-year-old NBA player has battled drug addiction for two years, and it reached the point last summer where she pressured him to go to rehab.
He did so, but Khloe Kardashian was so skeptical of his sincerity that she hired private investigators to wait outside 24/7 to make sure he didn't bail.
After three weeks and at least that many arguments over him leaving, he bolted for good, but did reportedly stay clean through the 2012-13 NBA season.
When the season ended this spring though, Lamar's recreational drug use returned. As for the persistent cheating rumors that have dogged him?
