In the startup game, star power only gets you so far.

Celebrities often use their fame and fortune to start businesses, but once the ventures are up and running, history shows that stars still succumb to some of the same hardships that trip up everyday entrepreneurs.

Some flops are truly perplexing, like Kim Basinger's infamous $20 million purchase of a Georgia town. Other celeb-owned businesses get stomped out because of more traditional obstacles, like Natalie Portman's vegan-friendly footwear line falling victim to the recession.

Such misfires haven't stopped many celebrities from trying and, sometimes, succeeding. Jessica Alba's new eco-friendly baby products site is gaining traction, P. Diddy has some notable notches under his belt, and Ashton Kutcher has proven himself to be a talented technology investor.

But for every Hollywood-fueled startup success, there's a celebrity-founded flop that will make you wonder, "What were they thinking?" Check out some of the most high-profile celebrity business failures:

  • Curt Schilling And 38 Studios

    As a pitcher in the MLB, Curt Schilling's <a href="" target="_hplink">love for video games</a> was well-known. But 38 Studios, the online gaming startup he launched after retiring, proved to be a tremendous flop. <a href="" target="_hplink">Schilling poured $30 million of his savings</a> into the company and the state of Rhode Island gave Schilling $75 million to build the company's offices in the state and hire local workers. But the fledgling company soon faltered. In 2012, 38 Studios failed to make payroll and <a href="" target="_hplink">laid off 379 employees</a> before declaring bankruptcy in June.

  • Natalie Portman And Vegan Shoes

    In 2008, Natalie Portman created a line of vegan-friendly footwear in a partnership with the New York City store Té Casan. The shoes, which retailed for a hefty $200 a pair, were created without fur, leather or feathers. Though one could say the price didn't help move product, the end of Portman's venture came less a year after launch, when <a href="" target="_hplink">Té Casan folded due to a poor economic climate</a>. <a href="" target="_hplink">The store put all of Portman's stock on sale in 2008</a> before closing up shop.

  • Hulk Hogan And Pastamania

    Whatcha gonna' do when lackluster profits run wild on you? Wrestling legend Hulk Hogan saw his fast-food restaurant, Pastamania, which offered pasta variations like "Hulk-U's" and "Hulk-a-Roos," <a href=",28804,2019716_2019715_2019741,00.html" target="_hplink">get choked out in 1995</a>. Despite promotional help from the World Wrestling Federation, the business closed its doors after less than a year. Perhaps Hogan should have <a href="" target="_hplink">put his name on the George Foreman grill</a> after all.

  • Britney Spears And Nyla Restaurant

    It wasn't long after Britney Spears opened her restaurant Nyla in June 2002 in New York's Dylan Hotel that bad publicity started destroying the eatery's credibility. <a href="" target="_hplink">Health violations, bad food and poor service -- not to mention, loads of debt</a> -- led to a major overhaul of the menu from Southern style dishes to Italian-style fare. The menu change didn't help. Spears would eventually abandon the restaurant, <a href=",,625179,00.html" target="_hplink">claiming that it fell victim to mismanagement</a>.

  • Kim Basinger And Braselton, Georgia

    Celebrities investing in startups and companies has become common practice -- but investing in towns? Actress Kim Basigner <a href="" target="_hplink">purchased the town of Braselton in her home state of Georgia for $20 million in 1989</a>. Basinger envisioned turning the town into a tourist destination, complete with movie theaters and a film festival similar to Sundance. Her big plans never materialized. She sold the town for <a href="" target="_hplink">$1 million in 1993, eventually declaring bankruptcy</a>.

  • Jennifer Lopez And Madres Restaurant

    Actress. Singer. Successful restaurateur -- not quite. Jennifer Lopez opened Latin eatery Madres in Pasadena, Calif. in 2002. The <a href="" target="_hplink">star-studded opening</a> reflected the restaurant's pricey fare, with dishes running between $30 and $50. <a href="" target="_hplink">Despite the prices and negative reviews</a>, Madres stayed open six years before closing its doors. <a href="" target="_hplink">No distinct reason was given for the closing</a>. Lopez has also seen fashion ventures go under. Her JLO line <a href="" target="_hplink">ceased to be profitable</a> and was closed in 2007, followed by the closure of clothing lines JustSweet and Sweetface. Still, Lopez has persevered through the failures, releasing a <a href="" target="_hplink">diverse, 51-look line for the department store Kohl's last year</a>.

  • The Kardashian Sisters And The Kardashian Card

    Reading the fine print is hard. The Kardashian sisters, Kim, Khloe and Kourtney, found this out the hard way while launching their very own credit card called the Kardashian Kard, aimed at young adults. <a href="" target="_hplink">Customer outrage began to mount</a> after reports surfaced that the card carried high fees, running cardholders at least $100 annually. The trio eventually backed out of their contract, claiming they were unaware of the card's high fees.
