The actress behind Gossip Girl's "Little J," Taylor Momsen, is seemingly determined to prove she's growing up. The 18-year-old's quest has included flashing the crowd as she toured with her band The Pretty Reckless, donning a dog collar around her neck, and apparently, not wearing pants. At MTV’s Europe Music Awards in 2010, Momsen stepped out in an incorrectly buttoned black top and not much else besides a whole lot of cleavage and eye makeup. "I don't really like pants, man. I like tights. I'm not really a pants person,” she told Entertainment Weekly early last year. "I choose not to wear pants."
