Lena Dunham Cut Her Hair Off! (PHOTOS, POLL)

"Girls" creator Lena Dunham isn't afraid to push the envelope on screen. Now, the 26-year-old actress has made a bold move IRL, chopping off her hair into a so-hot pixie cut.

Dunham, 26, posted a photo of her hair on Instagram, tweeting, "I Miley'd the shit out of this Saturday." (She was referring -- where have you been?? -- to Miley Cyrus' recent platinum blonde hair chop of her own.)

For proof, Dunham took her new hair out for a spin in front of some tough critics at designer Rachel Antonoff's New York Fashion Week spring 2013 presentation. (Dunham, if you haven't heard, is dating Antonoff's brother, fun. singer Jack.) Clad in a red sweatshirt reading "I'M WITH HER," the actress flaunted her new 'do -- but is it a home run? Check out the pics and vote below!
