Plight of the Living Dead: It's a Hollywood story that's sadly familiar: A child star grows up too fast, falls in with a bad crowd and pays with her innocence. At 16, Taylor Momsen thought she was an adult, but it turns out some parts of her matured faster than others. It started out as these things often do. She was just looking for some harmless fun, a way to unwind after a long day of listening to Dan delve into his teen angst on "Gossip Girl." And it sounded so cool and mysterious and darkly forbidden. Soon, however, she was hooked on the zombie high. No longer was the starlet satisfied with just a morsel of flesh or a nibble of tasty brain. She needed more. Much more. And the only way to get it was to hunt for it. So she suited up in her vampiest Elvira frock and went searching for fresh Goth flesh to gnaw on. Her first stop: a midnight screening of "New Moon."
