In the first report over the weekend, unnamed sources told TMZ that Odom, 32, has been using “hardcore recreational drugs” for the past two years and went to rehab last August. The report claims Odom stayed clean for the duration of the basketball season but started using drugs again once his run with the Clippers ended.
Reps for Odom and the Clippers have not returned PEOPLE’s multiple requests for comment. A rep for Kardashian Odom declined to comment.
A source close to the couple tells PEOPLE that Karshadian Odom has been struggling to help her husband. “It’s a really hard time for Khloé,” the source says. “She’s kept this secret for almost two years trying to save Lamar and their marriage.”
The 29-year-old “recently came clean and [her family] has been trying to help since,” the source says.
Another source who has known Odom for years says the couple have clashed over his partying: “Lamar genuinely doesn’t think he has a problem – it’s all ‘work hard then party hard’ with him until it goes off the rails. They really do love each other. But she really feels that this problem is out of control, and she’s hurt that he won’t get help.”
The couple has not been spotted together in public since June 2, and neither has commented on the status of their marriage, even following reports of infidelity allegations (which Odom has denied). On Thursday, Kardashian Odom was photographed looking unhappy and not wearing her wedding ring for a trip to the gym. On Aug. 25, she Tweeted, “Really hard to sit here and listen to people talk s— about my family … I’m too protective for this s—!”
“It’s absolutely heartbreaking for her,” the source close to the couple says of their struggles. “This is such a heavy load.”
