Drew Barrymore Back to Being a Blonde

What do you think of the actress hair transformation?

Drew Barrymore has lightened up.

Apparently, the light brown 'do that the actress debuted less than a week ago was just a step on the road back to blond, because Barrymore was spotted today rocking much lighter locks.

There's no word whether Olive's mommy made the change for a movie role or just for the heck of it, but the process was no easy feat.

With colorist-to-the-stars Tracy Cunningham laying down the foundation for Drew's look last week, the celeb was spotted hitting up a salon in West Hollywood today, where she's said to have spent roughly five hours to complete the transformation.

Which prompts the age-old question: Do blondes really have more fun?
