How To Get Your Ex Back Girlfriend jpg”>She may not seem like the smartest girl around, but Jessica Simpson is cashing out at the fashion bank.

After her famous question about “Chicken of the Sea” on the MTV series “Newlyweds,” Simpson became known as a ditzy blonde who no one expected to become a fashion mogul — or any mogul, for that matter.

However, she is proving that being successful within the fashion industry has nothing to do with her lack of knowledge about tuna.

Simpson is featured on the cover of this week’s New York Magazine.

According to the magazine, the Jessica Simpson empire racked in $750 million last year and is expected to push a jaw-dropping $1 billion this year as she expands her collection.

How this beautiful bombshell is managing to make it big in the fashion world? Jessica Simpson products are known for their stylish flare and affordable prices.

I admit, when she started her clothing line a few years ago, I chuckled skeptically; she definitely proved me and the rest of the world wrong.

With a large sales volume last year and an expected increase this year, Simpson has officially entered the big leagues. Large sales volume not only means entering the billionaire social club, but also the billionaire competition. The Jessica Simpson Collection is in competition with well-known designers such as the beloved Michael Kors.

While her current collection is composed of shoes (very, very cute shoes), purses, hair extensions, clothes and more, she still has plans to expand by adding a full ready-to-wear collection and a career separates line later this year.

The train doesn’t stop there; Simpson just launched a prom dress line at David’s Bridal. The new line features both evening and prom dresses.

Luckily for Simpson, her fashion endeavors have been successful. Celebrity brands often don’t live to see a runway or magazine advertisement past one year. However, some celebrities catch the eyes of fashion editors and big-time buyers at fashion week, hitting it big among fellow celebs and customers.

Celebrity brands like William Rast (Justin Timberlake), L.A.M.B. (Gwen Stefani) and The Row (Mary-Kate and Ashley Olsen) have all survived the celebrity clothing line catastrophe.

Simpson’s advice to struggling celebrity brands?

“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,” Simpson said. “Everybody doesn’t want to just look like the celebrity, because they can’t. They just want that element of style.”

Although she may not have graduated from Yale like her new fiance, Jessica Simpson is still smart enough to know how to create a fashion empire and cash a $1 billion check.
