Zosia Mamet Goes Blonde

Our favorite breakout Girls star, Zosia Mamet (also of Mad Men fame), has ditched her beautiful chestnut locks and gone blonde. She lightened up for her role as an untrustworthy and manipulative college girl in the Off Broadway play Really, Really. The color definitely suits her new part, as well as her quirky real-life Williamsburg style, but not so much her teeny bopper character Shoshanna. We're not quite sure how we feel about her transformation.

What do you think her new hair color?

P.S. If you are still wondering how to pronounce Miss Mamet's first name, it is ZAH-shah (like Sasha with a Z).
