3 – Lindsay Lohan
The last child star on our list is 29-year-old Lindsay Lohan who was only 11 years old when she starred as the adorable and mischievous freckle-faced twins in Disney’s remake of The Parent Trap.
Growing up on camera, Lohan landed starring roles in family friendly films like Freaky Friday and Herbie: Fully Loaded only to become a teen icon and household name thanks to her quintessential hit, Mean Girls, in 2004.
Making her way into the music industry, Lohan’s popularity and sanity unraveled for the world to see in 2006 when she was admitted to a California hospital for supposed dehydration.
Truth be told, her party-hard lifestyle had finally caught up with her. Arrested twice in 2007 for driving under the influence, Lohan checked into rehab for 45 days only to leave the facility and face another arrest for cocaine possession and driving under the influence. Despite more failed drug tests and stints in rehab, it looks as though Lohan might be back on the right track after making her stage debut in London in 2014.
