In the issue, she opens up about her public perception.

"I'm not a drinker, and when I'm up on the table dancing, it's for the picture," she says. "Then I sit right back down. I play into the perception of me, but it's not really me. And the show reveals that."

She credits her E! reality show for improving her self-esteem. "I used to think, I have to be this or that or skinny, and now, because of the show, everyone is embracing just me, which has given me such a confidence," she says. "Now, I’m like, 'Why did I ever give that feeling the time of day?' I’m so mature now. I’m a grown-up version of myself."

She's changed in other ways too.

Recalling her 2000 wedding to music producer to Damon Thomas (they divorced in 2004), she says: "For my wedding, I wore black leather pants, a black leather top, and Prada wedges. No flowers. And no family. It was so bizarre. I was a different person then — as I said, I always wanted to be a housewife, and I wanted to have kids at a young age. I was insecure and dependent, really the opposite of who I am today.”

When it comes to tabloid rumors about her life, Kardashian says, "I’ve learned to ignore everything. In the beginning I thought I was too sensitive for this. I’d Google myself and it would freak me out. Now I could care less if they say I’m pregnant with twins by my brother."
