Reese Witherspoon Goes Brunette
The 37-year-old went to the dark side once before for her role as June Carter Cash in the 2005 hit Walk the Line, which earned the actress an Academy Award for her performance.
Witherspoon's last outing was in Cabo San Lucas with her husband Jim Toth. The loved-up couple spent the Sweet Home Alabama star's 37th birthday at Capella Pedregal, one of the city's most romantic getaways.
