Gigi Hadid Rocks '60s-Inspired Pixie Cut for New Ad Campaign -- See the Pics!

Gigi Hadid, is that you?
The 22-year-old model seems to be channeling her inner Twiggy for her latest Stuart Weitzman campaign, sporting a cropped pixie cut and '60s-inspired thigh-high boots. 
"Gigi. Is. Back," the brand captioned a series of photos of Hadid rocking her new look on Instagram on Tuesday.

Photographer Mario Testino also took to social media to share the final product of the photo shoot. "THE NEW @GIGIHADID FOR @STUARTWEITZMAN!" he wrote.

While Hadid works hard on her new campaign, her sister, Bella, and pal, Kendall Jenner, have been living it up in Greece.
