Our favorite Charlie’s Angel wasn’t always so innocent. First noticed for her role of the cute little girl in E.T. The Extra-Terrestrial, Barrymore derailed at the young age of 9. It was then that she started smoking, by 11 she was drinking heavily, by 13 she was smoking pot, and by 14 she was doing cocaine and even went to rehab. Luckily, she’s sober now and still making hilarious movies.
