FameFlynet Pictures; startraksphotoReese Witherspoon has gone brunette! The star, who made serious waves at the Oscars with her perfectly-styled ringlets, debuted her new hue in Nashville over the weekend with her family. Witherspoon has worked her Legally Blonde highlights for years-the last time she crossed over to the dark side was in 2005 to play the role of June Carter-Cash, wife of country icon Johnny Cash. "My hair was dyed dark brown for Walk the Line," she told InStyle previously. "It was a very sophisticated style for me." We think it looks just as chic the second time around!
