Here’s supermodel Gigi Hadid … proving she’s one hell of an athlete — by hitting a heavy bag — IN HEELS!!!
Hadid hit up Gleason’s Gym in Brooklyn — and despite the fact she was wearing (what appeared to be) leather leggings and chunky heels … she went all Rocky Balboa anyway — and looked damn good.
Gigi’s been boxing for a while — and she’s picked up a pretty solid overhand right.
