A newly blond Jessica Alba swung by Jenni Kayne's store in West Hollywood yesterday. Jessica, who recently lightened her hair to reprise her role as a stripper in the upcoming sequel to Sin City, was already wearing a pair of D'Orsay flats from Jenni's line when she showed up to shop. Changing her locks isn't the only thing she's done to prepare for her next part. Earlier this week, Jessica visited a shooting range to practice her marksmanship. She's spent much of her Summer at home in LA focusing on her next film, her family, and her business venture, The Honest Company. In July, however, she took a time out to visit NYC and to take her daughters and mother on an Italian getaway.
