Lindsay Lohan

Probably one of the very few stars that Disney isn't really proud of churning out, LiLo has definitely let down the world despite her innumerable attempts at getting her life right, all thanks to her drug addiction. Her first stint with Disney was in the Parent Trap in 1998, followed by Freaky Friday in 2005 and Herbie: Fully Loaded, and of course with the box-office success came the fame and the trauma that soon ensued. Her career went straight downhill and there was no turning back. We do really hope she gets herself back on track soon enough.
