Lamar Odom is owning up to the role he played in his split from Khloe Kardashian.

While married, Khloe and Lamar had an E! reality series, and while the 37-year-old athlete says he doesn't necessarily regret doing the show, he does say it "opened this gate up with other women who probably wouldn’t have been interested" in him. "When I became Khloe Kardash­ian’s man and on TV, it made me look more enticing," he tells Us Weekly. "People who didn’t even know basketball would approach me because they knew Lammy."

Lamar confesses that he was unfaithful to Khloe after women "came out of the woodwork."

"If there is one thing I regret when I was married, it was having multiple affairs with different women," the former NBA pro continues. "That wasn’t the stand-up thing to do."

In December 2013, Khloe and Lamar announced their split after four years of marriage, but Lamar says he was doing drugs long before their breakup. "I was hiding it for a while, but then I got frustrated and was like, f**k it. Around two years before we split up, I was in the man cave she had made for me and she caught me. She was disappointed. So was I," he recalls. "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."

"[Khloe] knew I was doing cocaine the whole time after that. It was my drug of choice," Lamar adds. "I’m not going to say she accepted it because that would be the wrong word. Tolerated would be a better word."

In October 2015, Khloe put her divorce on hold from Lamar after he was found unresponsive in a Nevada brothel and remained unconscious for several days. Lamar says when he finally woke up, there was a "moment of relief" when he saw Khloe by his side.

"She was the first thing I saw. She said, 'Hi, Mookah.' 'Mookah' is a name my mother used to call me. She said it to let me know I wasn’t dead," he recounts. "She played a major role in me getting my memory back. 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."

Last January, Khloe admitted on Howard Stern's Sirius XM radio show that she never thought Lamar was unfaithful to her. "Lamar was so great at making me feel like I was the only one and I'm this princess," the 32-year-old reality star recalled. "I never speculated cheating."

Khloe and Lamar eventually signed off on their divorce paperwork in October of last year, and their marriage was officially terminated two months later.
