This Is How Pregnant Megan Fox Kicked Butt On The Set Of 'Ninja Turtles'

Now that's one seriously impressive momma.

Did you know Megan Fox was pregnant while working on "Teenage Mutant Ninja Turtles"? Well, now you do because that is, in fact, a true story.

And while incubating a tiny human-to-be in one's belly is a hard enough job as it is, Fox managed to make things even harder for herself by working on a movie that had stunts and tricks aplenty (in addition to hanging around in sewers for hours on end). To say nothing of acting alongside CGI mega-turtles.

MTV News got a few minutes of director Jonathan Liebesman's time and asked him just how well Mama Fox did in the high-octane environment. "Megan's a great mom and that's super important to her," he said. "We wanted to be very respectful."

Turtle power has never looked so impressive!

"Teenage Mutant Ninja Turtles" opens everywhere on Friday, August 8th, 2014.
