Reese Witherspoon is no longer legally blonde.
The actress debuted a new, darker 'do in Nashville yesterday when she was spotted rocking a brunette look instead of her usual blond tresses while out to lunch with hubby Jim Toth and their baby, Tennessee (so cute!).
So what prompted Reese to switch to the dark side?
Usually, a new movie role is behind a drastic switch with the 'do (unless you're Rihanna), but there's no word on a specific project causing the change, so maybe her recent birthday celebration inspired the new hair (regardless, who doesn't like to mix things up a bit from time to time?).
Witherspoon kicked off her 37th birthday by heading to Cabo San Lucas with her hubby for a romantic, kids-free vacay last week. The couple stayed right on the beach in a one bedroom suite that had a private pool, a source told E! News, with the birthday girl spending her days lying by the pool, tanning and relaxing.
Ah, the life.
