Karen Gillan Bares Shaved Head for 'Guardians of the Galaxy'!

Karen Gillan takes her wig off and bares her new bald head while posing on the Marvel Studios Press Line during 2013 Comic-Con on Saturday evening (July 20) in San Diego, Calif.

The 25-year-old Doctor Who actress revealed her bald head during the panel for Guardians Of the Galaxy, where she plays villain Nebula.

“It’s liberating. I think everyone here should shave their heads,” Karen shared on the panel.

Just the day before, Karen was spotted wearing a red wig around the annual event, stopping by the Wired Cafe and the Nintendo Oasis on the TV Guide Magazine Yacht.
