Occupation: TV host, entertainment mogul
Seacrest may be best known for co-hosting American Idol, but he logs a great many more hours in his other gigs, hosting a five-hour radio show and helming E! News. All the while, he is overseeing a budding entertainment empire, Ryan Seacrest Productions, which is behind reality shows like Keeping Up with the Kardashians and just received a $300 million cash infusion from two major investment firms. But as he showed after Sacha Baron Cohen spilled an urn full of "ashes" on him at the Oscars, it's Seacrest's suave, unassuming style that keeps him in Hollywood's good graces.
