Drew Barrymore is one of the biggest names in Hollywood, but it hasn't always been easy for the former child star. In fact, the actress's path to success was exceptionally rocky. In honor of her 39th birthday on Feb. 22, take a look back at the highlights -- and lowlights -- from Drew's first four decades in the spotlight.
Hollywood is part of Drew Barrymore's DNA. The daughter of actor John Drew Barrymore and actress Jaid Makó Barrymore traces her Hollywood lineage back to silent film actor Sidney Drew. Even her godparents, director Steven Spielberg and actress Sophia Loren, are film legends. So it's no small wonder the California native made her acting debut at an early age: in a commercial for Puppy Chow when she was just 11 months old.
