Reality TV shows: Laguna Beach: The Real Orange County (2004-2006), The Hills (2006-2010)

How episode after Hills episode of petty drama concerning Conrad's vapid ladyfriends and toolbag dating prospects turned her into a pop culture fixture...we'll never truly understand. However, it's got to be said that other reality stars should take notes from this girl—she knew her audience well and just how to capitalize on that fanship.

The end of Conrad's MTV stint very well could've marked the beginning of the end, but on the contrary, it was the beginning of the beginning. In addition to launching her successful eponymous clothing line for Kohl's, her L.A. Candy series of young adult novels earned her a spot on the New York Times Bestseller list, as well as her subsequently released style guide. She now has additional books in the works, along with a potential movie.
