"I definitely went through a wild phase, I would say in my late teens," Kim said. "I'm not like that anymore. But I still have fun — don't get it twisted, I'm always the life of the party."
Kim secretly eloped with first husband, music producer Damon Thomas, in 2000 when she was just 19. The couple split in 2003 and that same year Kim made her now famous sex tape with then boyfriend Ray J.
The tape was released in 2007, coinciding with the first season of Keeping Up With the Kardashians.
Kim previously claimed she wasn't a big partier and served as the designated sober driver for her friends during her teens.
"Kim does not drink alcohol whatsoever. Pregnant or not, she's just never been into it," sister Khloe Kardashian told Elle in 2016.
In 2017, Kim denied using cocaine after fans spotted a suspicious mark on her coffee table — which turned out to be just marble — in one of her Snapchat videos.
