Jessica Simpson Entering The Billion Dollar Club

Jessica Simpson may not have gone to Harvard and created Facebook like Mark Zuckerberg, but the blond pop singer is about to have something in common with the social networking kingpin - she's joining the ranks of young billionaires.

Jessica's fashion line, which includes shoes, purses, hair extensions, clothes and more, is gearing up to make $1 billion in sales this year, according to New York magazine, which features the chanteuse on its cover.

"I never thought I'd be some fashion mogul!" Jessica told the magazine of her move from the big time -- $750 million in sales last year - to the even bigger time.

Jessica said she doesn't try to concentrate on having a "trendy" collection, rather she is putting the main focus on "basics."

"We try not to set trends, but you need your trending pieces in every delivery. But those go fast. What you really need is your basics for every type of person," she said. "When it comes to other celebrity brands, I think a lot of people do a great job, but it can't be all about them. Everybody doesn't want to just look like the celebrity, because they can't. They just want one element of that style."

Like her customers, Jessica likes to look stylish. She's tried a host of trends herself over the years, including those high-waisted jeans on stage in 2009 that made international headlines.

"I still thought I looked cute," she said of the infamous outfit. "I wouldn't have gone onstage if I didn't."
