Occupying the spot in our list once dominated by Britney Spears, Lindsay Lohan is another child star turned troubled adult. Lohan first appeared in the Top 10 Searches in 2005, when she was flush with success from "Mean Girls" and her new album. Since then, her fortunes have waned as she has gone through a revolving door of rehab. Lohan fell off the list in 2009 and 2010 but reappeared last year with the notoriety over her frequent court appearances.
With the end of her probation in 2012, she chronicled some hopeful turning points, including a primetime "Glee" guest episode and several projects—notably her turn as the late Liz Taylor and a photo shoot in Playboy. But November brought more bad news from both coasts: Lohan was charged with crimes in New York and Los Angeles.
