A cast of real-life celebutantes (i.e. children of actors, party girls and reality TV stars)play snooty sorority girls who are being stalked and hacked to death by someone who's just had enough in the new slasher flick 'Sorority Row.' The premiere took place yesterday at the ArcLight Hollywood, where Demi Moore escorted daughter (and cast member) Rumer Willis, Carrie Fisher posed with other 'Sorority' girls Caroline D'Amore, Audrina Partridge, Briana Evigan and Jamie Chung, and goofy-good looking Ron Livingston smirked on the red carpet.
