This weekend, Scarlett Johansson attended Comic Con (looking stunning in an all-black Dolce & Gabbana pantsuit) to reveal her new role as the Black Widow in the upcoming flick The Avengers. But she also revealed something else--her brand new locks! She transformed her signature long strands into a center-parted, slightly rumpled long bob, and we love it. The style is relaxed, youthful and a fabulous juxtaposition to the serious suit she rocked while touting her latest gig. But Johansson isn't the first to lop off her locks: It appears that several celebrities are forgoing their former styles in favor of the LOB (read: long bob). What do you think of Johansson's latest look? Tell us in the comments section below!
