Jessica Alba modeled freshly dyed locks yesterday when she arrived at a firing range in LA. The actress is the midst of making a physical transformation for her upcoming role in Sin City: A Dame to Kill For. Jessica began changing her look last week when she dyed her hair. She followed up with a second visit to her hair salon on Saturday that resulted in her current shade of blond. Jess landed the role of Nancy Callahan in the sequel to Robert Rodriguez's Sin City, and in addition to making a drastic change to her hair, it appears she's also brushing up on her shooting skills. The film is set to begin production before the end of Summer and is currently slated for an October 2013 release.
