She's been blonde her whole life, but Gossip Girl star Blake Lively says she liked switching up her style for her new movie: "For Green Lantern, I was a brunette . . . I loved having the brown hair."

"This man, who I’ve never heard him say more than four words - you would never pin him as a comic book fan - as soon as it came out that I was playing Carol Ferris/Star Sapphire, he was like, 'You have to dye your hair brown!' He said, 'Not only for my sake as a fan, but for your own security, I’m telling you, you have to dye your hair brown! People will attack you, people will be so angry.'"
