Ryan Seacrest

Ryan Seacrest is the current host of the wildly popular televised singing competition, American Idol, as well as the long-running reality show Campaign!.
It is also widely believed that Seacrest is secretly a space alien -- albeit a space alien whose origins have been well-hidden with major plastic surgery and frequent body waxings -- named Gordon Shumway, whose exploits throughout the late 1980s were chronicled on NBC's reality show ALF.
