Drew Barrymore

It’s hard to imagine that the happy-go-lucky, Hollywood powerhouse, and mother of two that is Drew Barrymore is the same child star who was forced to enter rehab at the tender age of 13. Thanks to films like ET, Barrymore was a massive star by age 7. Unfortunately, this led to taking part in the LA party scene by age 11, and the aforementioned rehab stint by middle school.
