To the paparazzi, Kim Kardashian is the party pal of Paris Hilton and Nicole Richie.

But if you think that's all there is to the Hollywood hottie, think again!

The brunette beauty invited "Extra" to Dash, the upscale boutique that Kim and her sisters, Courtney and Chloe, built with their own money and labor.

"I'm a business woman," Kim assured us. "I'm not the crazy, wild party girl people think I am. I don't even drink alcohol, I don't even smoke."

But Kim does love fashion, and her sense of style brings out the stars.

"We have everyone from Paris and Nicole to Rebecca Romijn; Denise Richards," she dished.

She even caters to moms-to-be, like FOX's "Good Day Live" starlet Jillian Barberie, who is in her 6th month of pregnancy.

"My boobs have a zip code of their own," Barberie joked, adding that she values Kim's opinion.

"Wrap dresses are really perfect to kind of cover your belly ... A lot of 70's inspired prints," Kardashian said. "Really short shift dresses. All of these look like maternity dresses anyway."

But Kim's opinions don't end with fashion; she also has a lot to say on everything, starting with what makes people sexy: "When you start doing things that make you feel good, you build up a confidence, and confidence is sexy."

Kardashian also opened up about the mistakes she may have made in life.

"I try not to say that I've made mistakes even if they seem really stupid, as long as you learn from them," she said. "And I really try to learn from the poor choices I've made."

Kim credits mom Kris and step-dad and former Olympic champion Bruce Jenner with keeping her grounded. She also thanks her godmother, Kathie Lee Gifford, for the best advice a young woman could ever get.

"She said, 'If you find what you love to do and figure out a way to make money at it, you'll be happy,'" Kim shared.

And from the looks of it, this young businesswoman is well on her way to a happy life!
