The model’s shimmering silver Tommy Hilfiger gown -- especially while on the Versace-designed robotic arm of her boyfriend -- fit perfectly with the 2016 Met Gala’s “Manus X Machina: Fashion in an Age of Technology” theme. This was the year the couple made their red carpet debut, and four years later, it was announced that they are currently expecting their first child.
