Megan Fox shows off her teeny-weeny waist as she shoots her new movie, Jonah Hex, on Thursday (April 23) in Louisiana.

Folks, these pictures are not Photoshopped and that waistline is 100% real. Megan looks like she’s laughing… because she can’t breathe!!! As for her real waist size, guesses anyone?

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!
