In an effort to promote "Jennifer's Body", Megan Fox shot one tickling public service announcement (PSA), and the video has been made available for viewing pleasure by Break. Addressing the peer pressure issue among high school students, the lead actress in the horror comedy film tells youngsters to "be yourself", "even if it means killing and eating every boy at your school."

From the noted "Juno" screenwriter, Diablo Cody, comes a new comedy thriller film about Jennifer, a beautiful cheerleader possessed by a demon. Due to her current state, she seduces boys in a Minnesota farming town to feed off them. Now, it is left to her nerdy best friend Needy to save the boys and stop Jennifer from killing all the boys.

Starring the "Transformers: Revenge of the Fallen" beauty as Jennifer, the movie directed by Karyn Kusama also sees Amanda Seyfried as Needy. The two leading ladies will be supported by the cast that consist of Adam Brody, Amy Sedaris, J.K. Simmons, Chris Pratt and many others. It is expected to come out September 18 in U.S. theaters.
