Ladies and gentlemen, prepare for your jaws to drop to the floor.

Because Megan Fox has just been pictured wearing a Britney-Spears-Hit-Me-Baby-One-More-Time-style school girls outfit.

And the mum-of-two looks schermaze.

Showing off her toned figure in a little grey rah-rah skirt, a white tied up shirt and knee-high socks, Megan worked her ensemble as she filmed scenes for Teenage Mutant Ninja Turtles 2.

Donning a cropped blonde wavy wig and specs, we had to double take to check this was actually the same Megan Fox we all know and love.
