Maggie Gyllenhaal is about to have all the fun! The Honourable Woman star, 36, showed off her new blonde pixie cut in Cannes, France on Monday, April 7. 

The mother of two has sported her short 'do for more than a year, but hasn't been photographed with platinum locks before. 

"In Cannes with The Honourable Woman.  I'm blonde btw...@mariesalon," Gyllenhaal wrote, tagging Marie Robinson Salon in New York. 

Gyllenhaal, who lives with her husband, actor Peter Sarsgaard and their two daughters Ramona, 7, and Gloria Ray, 23 months, in Brooklyn, N.Y., filmed the TV mini series in the U.K. and Morocco. She stars as Nessa Stein, the daughter of a Zionist arms procurer who witnessed her father's assassination as a child. 

The Honourable Woman will air on BBC Two in the U.K. on April 7, and on Sundance TV in the U.S. later this year.
