It was date night for sisters Gigi and Bella Hadid and their respective musician boyfriends, Zayn Malik and The Weeknd, at the 2016 Met Gala. The elder Hadid, who just celebrated her 21st birthday, sported a gunmetal gray Tommy Hilfiger Collection gown complete with a metallic bodysuit, while Malik donned a Versace single-button suit with metal robot-like sleeves.

Bella and The Weeknd went for slightly more understated all-black looks. The model's strapless cascading Givenchy gown was all about classic glamour, as was The Weeknd's monochromatic tux.
