At 17, Lindsay was on top of the entertainment world. She had two huge hits on her hands -- "Freaky Friday" and "Mean Girls" -- and lots to celebrate. So she went out to clubs and partied with the big kids, drinking and doing drugs. But things got really bad for Lindsay really fast, and her partying started to get in the way of her health and work. In July 2006, studio executive James G. Robinson wrote a letter to Lindsay calling her "irresponsible and unprofessional" for her "ongoing all-night heavy partying" during the making of "Georgia Rule." Then, in May 2007, 20-year-old Lindsay was nabbed for what would be the first of many DUIs. After four stints in rehab, she is back at work and staying out of trouble.
