Is there any other way to celebrate the 50th anniversary of the Sports Illustrated swimsuit issue than with a supermodel-filled party? We spotted Kate Upton, Heidi Klum, and Chrissy Teigen looking especially sexy on the red carpet. While Kate showed off her bombshell figure in a curve-hugging black maxi dress with gold seamwork, Heidi and Chrissy opted for looks that showed off their legs. Heidi was the lady in red — red leather, to be specific — with her moto-jacket-inspired dress and matching pumps, while Chrissy shimmered in a black sequin jumpsuit accessorized with a metallic clutch and coordinating heels. While these women were all in head-turning looks, which star do you think modeled perfection on the red carpet?
