On an episode of Keeping Up With the Kardashians last month, Kim admitted that she was high on ecstasy for both her first wedding and the taping of her sex tape.

“I got married on ecstasy. The first time,” Kim said, referring to her 2000 marriage to Damon Thomas. “I did ecstasy once and I got married,” she added. “I did it again, I made a sex tape. Like, everything bad would happen.”

On Busy Tonight, Kim told host Busy Philips that momager Kris Jenner knew about Kim’s drug use, and she was way less than thrilled.

"I would tell my mom everything, we always had such a close relationship," Kim said. "So I would come home and be like, ‘Oh my god, mom, I did ecstasy last night.' I remember this so clearly, she was sitting on top of the washing machine, she had jumped up on it and we were sitting in the hallway… and she was like, 'You, one day, you’re not going to be able to have babies, you can’t do this, you’re going to ruin yourself!' Like, she was so upset. And she never did drugs, so she was just so upset.”

Kris was concerned that Kim would "just be this crazy drug addict," and the 38-year-old eventually agreed with her mother. "I just was like, 'You know what? She’s so right, I’m so over it,'" Kim said. "Like, this is so not me. And I just never did anything again."

While it's surprising that Kim has done hard drugs at all, given the fact that she doesn't drink or smoke, it seems those days are behind her now that she's a mom and a successful businesswoman.
