Megan Fox [1] slipped back into her skinny jeans to film reshoots for Teenage Mutant Ninja Turtles on Tuesday, just seven weeks after the actress gave birth to her second child [2], Bodhi Ransom Green. Donning serious boots, Megan scored some cardio as she ran toward the camera. All the action had her long brown locks blowing in the wind. It didn't all look so glamorous, though — at one point, the actress filmed a scene next to a dumpster! Megan first revealed her postbirth body [3] during a casual errand run in LA, stepping out five weeks after she brought Bodhi into the world. If you can't wait to see her back on the big screen, check out the bodacious trailer teasing Megan's movie [4] with our favorite family of turtles.
