Megan Fox

The poster is out for her upcoming horror movie, "Jennifer's Body," and it's all over the Internet already.

This is the movie where Fox plays a demon-possessed high school cheerleader on a male killing spree. “I start eating the boys in my high school,” she told "Access Hollywood" of the role. “[It’s] one of the best scripts I’ve ever read.”

"Juno" screenwriter Diablo Cody wrote the film, which also stars Amanda Seyfried of "Mamma Mia!" and Adam Brody of "The O.C." co-star.

The movie comes out Sept. 18.
