Kim Kardashian Is 'Freaking Out' About Turning 30

Kim Kardashian is celebrating her 30th birthday in a big way. First, there was her saucy W magazine cover. Then, her official birthday parties: one in Las Vegas and one in New York City, where she and her sister Kourtney just relocated.

When MTV's "The Seven" caught up with the reality-TV phenom at her Vegas bash, she and her sisters admitted some pre-birthday jitters.

"Kim is really nervous about being 30," Khloé said.

"I'm freaking out," Kim admitted.

Regarding her headline-generating magazine cover, upon which Kim appears very scantily clad, the TV star/ entrepreneur said the opportunity and the timing were too good to refuse.

"The cover of W is iconic," Kim said. "I just thought, why not? I'm turning 30, and there are probably some things you can't do after you turn 30, so I might as well do it while I can.

"30 is the new 20, blah, blah, blah, I get it," she added. "All jokes aside, I think it will be really refreshing and fun. I feel really accomplished."

Kim has said she's in a really comfortable, confident place in her life now. "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 told W magazine. "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 also learned not to take herself too seriously and to ignore everything that's written about her in the media. "In the beginning, I thought I was too sensitive for this," she said. "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."

Don't miss "The Seven" every weekday at 5 p.m. ET on MTV.
