Lamar Odom exclusively spoke with the folks at Us Weekly about his past drug abuse. And during the candid moment, he explained how his ex-wife, Khloé Kardashian, found out.

In the cover story, he revealed that the reality star caught him shooting up two years before they called it quits.

"I was hiding it for a while, but then I got frustrated and was like, f**k it," he said. "Around two years before we split up [in 2011], I was in the man cave and she had made for me and she caught me. She was disappointed. So was I. The sad thing about it is, I don't know if I was disappointed because I was actually doing the drug or because she caught me."

He added that after that moment, she was fully aware that he was an active drug user, but "tolerated" it.

"She knew I was doing cocaine the whole time after that," he said. "It was my drug of choice. I'm not going to say she accepted it because that would be the wrong word. Tolerated would be a better word."

The athlete also went into detail about the night he ended up at the brothel in Nevada, explaining that he was "home by himself" and "bored."

"I wanted to go out and have a good time," he said. "Looking back, I might have had a drink to get the mood started, but was I drunk or on drugs? Not at all. I remember lying in bed. Two women were in bed and then I fell asleep. That's all. When I woke up four days later, I was trying to pull the tubes out of my mouth."
