JESSICA SIMPSON

American singer Jessica Simpson has earned a sizable fortune as a retail entrepreneur. Her line of handbags, beauty products, and shoes has generated over a billion dollars in gross sales as of writing. As for her IQ score, it might seem unbelievable, but she’s actually in the same intellectual stratosphere as astrophysicist Stephen Hawking and Microsoft CEO Bill Gates! Yes, Simpson reportedly has an IQ of 160!

The singer-turned-entrepreneur got a promising start in the 1990s alongside Britney Spears and Christina Aguilera with her wholesome major-label debut Sweet Kisses, which sold over 1.8 million copies. Her follow-up album, Irresistible, sold just over 600,000 copies. Outside music, Simpson also broke into movies and landed the acting credit of Daisy Duke in the big-screen version of Dukes of Hazzard. She is married to former football professional player Eric Johnson, with whom she has three kids.
