Gigi Hadid's bob at the AMAs has got the whole world talking, but the model isn't the only one to show off a dramatic new hairstyle this year

From Lara Bingle's shock pixie crop to Jennifer Lawrence's sexy platinum shlob, celebrities everywhere have been quick to chop off the luscious long locks we usually see on red carpets - right now, the shorter, the hotter.

We think Charmed actress and one-time Marilyn Manson lover Rose McGowan might have taken things a step too far when she shaved her head this week (for 'liberating' purposes apparently), but we can't get enough of Scarlett Johansson's bold pixie cut, Katy Perry's sophisticated jet black lob (does anyone else think she looks like Monica from Friends now?) and Sienna Miller's gorgeous strawberry blonde, collarbone-grazing waves.

Lily Collins is one of the few bucking the trend: an early adopter of the pixie cut, she's welcomed back long hair care of some very convincing extensions. Seeking fringe inspo? Look no further than the blunt-cut bangs Ciara showed off front row at Givenchy during NYFW, Dakota Johnson's full fringe and Kendall Jenner's brand new bangs.
