11. MEGAN FOX AS JENNIFER CHECK IN JENNIFER’S BODY (2009)

Jennifer Check’s (Megan Fox) first mistake is being a groupie for a trashy rock band led by Adam Brody—he makes Jon Bon Jovi seem like Iggy Pop. Against her best friend’s (Amanda Seyfried) wishes, though, Jennifer boards the band’s minivan after a freak technical malfunction turns the venue into an inferno. You might be asking yourself, “Wouldn’t nearly burning to death leave her a bit too flustered to ditch her girl for some potential groupie love?” Of course. Obviously, screenwriter Diablo Cody is no Aaron Sorkin.

But complete disregard of common sense isn’t Jennifer’s worst deed. The rockers are actually devil worshippers; instead of giving Jen an all-access pass, they cast a demonic spell on her that turns the once-insecure cheerleader into a confident, man-eating succubus. It doesn’t get much naughtier than swallowing a guy’s intestines behind closed doors. Needless to say, she doesn’t spit, either.
