Karen Gillan stepped out at the Comic-Con International 2013 on Saturday sporting bright red hair - before removing it and showing off her bald head to the world.
The actress was speaking at the Marvel's Guardians Of The Galaxy panel when she shocked the audience by revealing the dramatic hairdo.
The former Doctor Who star shaved her head for her role in the flick, which sees her playing baddie Nebula.
Karen was all smiles while revealing the transformation, and was cute in a daisy-print tee, denim shorts and biker chick boots.
Well, if anyone can pull off the look, Karen can.
