Lamar Odom believes he's "a walking miracle" after being found unconscious with cocaine in his system in a Nevada brothel in 2015.
Odom told US Weekly he hid his cocaine use from ex-wife Khloe Kardashian for a while, but she found out about two years before their 2013 split.
"[In 2011], I was in the man cave she had made for me and she caught me. She was disappointed. So was I... I’m not going to say she accepted it because that would be the wrong word. Tolerated would be a better word," he told the magazine.
Odom said he "turned the drug use up to another level" after he and Kardashian split.
He also revealed that he regrets "having multiple affairs with different women" while married to Kardashian.
"That wasn’t the stand-up thing to do," he admitted.
Kardashian filed for divorce in 2013 but delayed it after the incident at the brothel.
Odom said Kardashian helped him regain his memory following the episode.
"She would bring pictures of my mother and my grandmother. I kept thinking, Am I paralyzed forever? Am I mute forever? It was scary s--t. Faith got me through."
Their divorce was finalized in December.
Odom blamed cocaine for helping end his NBA career. He says "drugs killed my drive to want to train and be in shape."
He said he's sober now after finishing a rehab stint in January.
