Jennifer's Body (2009)

Sexy temptress Megan Fox (Transformers) is hotter than hell as Jennifer, a gorgeous, seductive cheerleader who takes evil to a whole new level after she’s possessed by a sinister demon. Steamy action and gore galore ensue as the male student body succumbs to Jennifer’s insatiable appetite for human flesh. Now it’s up to her best friend (Amanda Seyfried; Mamma Mia!) to stop the demonic diva’s reign of terror before it’s too late!
