Playing the resident mean girl on the hit show *Gossip Girl* has made actress Michelle Trachtenberg a bit notorious with the show's young fans. "I try not to walk around the city too much at like 3 p.m. when school lets out," she jokes. "Hordes of school kids come out and they're like, 'Oh my God, she's scary!' It doesn't work well for my mental psyche!" The 24-year-old who's been acting since she was 3 years old also plays a nurse on the NBC drama *Mercy,* and makes time for a third job: jewelry designer for Coach's Poppy Collection! "It's all hearts and keys, and it will be out for Valentine's Day because you have to love and unlock your heart!" Rachael notices that the young star is also wearing a gem on her wedding ring finger, but Michelle clarifies that she's still single. "It's just to keep the creepy old dudes away!"
