Kate Upton aced tennis chic at the US Open on Saturday.
The 21-year-old Sports Illustrated swimsuit model (not to mention the "hottest supermodel on Earth," according to Vogue) looked fresh-faced and sporty while watching the men’s semifinals along with fellow model Karolina Kurkova.
Upton wore a white Robert Rodriguez dress that accentuated her voluptuous curves, along with Ray-Ban sunglasses, nude sandals and minimal gold jewelry.
