After going through a very public divorce with Kris Humphries, Kim Kardashian admits she is “totally growing up” these days, changing a lot about her lifestyle. Oprah touched on that topic and finally got Kim to dish on the infamous sex tape that launched her career…

Over the weekend, the first part of Oprah Winfrey’s highly-anticipated interview with the Kardashian family, ‘The Next Chapter,’ aired, and the most famous Kardashian told the TV icon that she is a whole new person these days. Following her 72-day marriage to Humphries, the reality show star hunkered down away from the spotlight to deal with her grief as privately as she could, but after emerging back into the limelight, the world noticed a more mature Kardashian who had her head on straight, considering the humiliation and whirlwind that surrounded her and her family during that time.

Speaking of humiliation, Oprah addressed the elephant in the room: Kim’s sex tape. Oprah asked her point blank if she would have a career without it and Kim admits that was how a lot of people found out who she was. “That’s pretty much how I was introduced to the world. It was a negative way, so I feel like I had to work 10 times harder to get people to see the real me,” adding that she was humiliated by the whole affair. (For her part, Kris Kardashian said she cried herself to sleep the few nights after the sex tape was leaked.)

But now, Kardashian is dating another public figure, Kanye West, who happens to be four years older than the 31-year-old. “I love that I’m with someone who is a couple years older than me,” she said of dating West. “I love that my friends are even sometimes 20, 30 years older than me.”

Kardashian went on to compare her growth and maturity to her older sister, Kourtney, when she gave birth to her son, Mason, back in 2009. “Kourtney had this epiphany when she had the baby, and she changed into a different person,” she said of her sister. “I feel like I’ve had an epiphany over the last year for what I’ve been through, and I am that changed person just from my own experiences.”

Look for Winfrey’s second part of her interview with the Kardashian clan when it airs on Sunday, June 24 at 8:00PM ET on OWN and be sure to stay tuned for any highlights you might miss.
