Spencer Pratt

Throughout its history, Hollywood witnessed its share of great leading men, from Humphrey Bogart to Marlon Brando to Denzel Washington. Spencer Pratt, however, was not one of them. But the notorious tabloid personality managed to capture America's attention by shamelessly promoting his personal life and commercial exploits with girlfriend/fiancée/protégé Heidi Montag, to whom he proposed marriage in May 2007 on their reality show, "The Hills" (MTV, 2006-10). Despite insisting that their "candid" photos in magazines like US Weekly and In Touch or turbulent relationship on "The Hills" was real, few really bought it. Then again, because of their ubiquitous presence throughout the media landscape, both he and Montag carved out lucrative careers without anyone really knowing just why they were famous in the first place.
