Chloe Moretz, the 13 year old breakout star of buzz movies like Kick Ass and Let Me In, has been tweeting up a storm (@chloegmoretz) about all manner of things, most recently that she's in New York. Why is she in New York, you ask? To shoot an episode of NBC's"30 Rock!" This is good news for people who like peanut butter and jelly sandwiches, cheddar cheese and pretzel Combos, and the Run DMC/Aerosmith collabo "Walk This Way." Moretz was by FAR the best thing about Kick Ass, and "30 Rock" is all that is right with single camera sitcoms, so this appears to be a match made in showbiz heaven. There are no details on her role on the show yet, but one could speculate that she plays a gun toting vampire who murders everyone that works at the fictional sketch show "TGS."   (Vulture)
