20th Century Fox has debuted the first red band trailer for Jennifer's Body starring Megan Fox and Amanda Seyfried!

Described as a Heathers-like dark comedy, Jennifer's Body tells the story of a seemingly-perfect cheerleader whose life is thrown into disarray when she gets possessed by a demon, begins eating boys in her small town, then faces off against her best friend and the Satan-worshipping band that made her evil. Fox will finally bring Jennifer's Body to theaters on September 18th later this year.
