Megan Fox was spotted on on the set of the period western comic book flick ‘Jonah Hex’ last week. The “Transformers: Revenge of the Fallen” hottie showed off her teeny-weeny waist as she stepped out onto the lot sporting a super-sexy black corset-style ensemble along with thigh-high boots and a cape.

In the flick, the 22-year-old actress plays Leila, a gun-wielding beauty and love interest of scarred bounty hunter Hex (Josh Brolin). A super hot one at that!
