While Gigi Hadid rocks the runway at New York Fashion Week, her sister Bella's holding down the fort on the red carpet in LA. The model joined her beau, The Weeknd, at the Grammys in one of the sexiest looks she's worn yet: an Alexandre Vauthier Haute Couture number with a plunging neckline, cutouts, and a leggy slit. It's safe to say Bella left everyone breathless as she struck a fierce pose, showing off her strappy leather heels and a handful of eye-catching Bulgari accessories: a Serpenti cuff, Corona diamond studs, and an edgy box clutch.
