2. Drew Barrymore
Drew Barrymore was only 9 years old when she landed her big break through on one of the most iconic movies of all time, “E.T. The Extra Terrestrial”.
However, this young starlet was by no means innocent as she started smoking by the eager age of 9 and then she started drinking by age 11. She even went to rehab at the young age of 14 years old.
Today, she has cleaned up her act and she continues to star in comedic movies along with being the producer of multiple TV shows such as “Blooms” and “Santa Clarita Diet”.
