They are always where the action is, and on Saturday (September 7) Kate Upton and Karolina Kurkova took in day 13 of the U.S. Open in New York City.

Lovely in their designer frocks, the two supermodels sipped on champagne at the Moet & Chandon suite as they watched players battle it out on the court below.

On Wednesday, the Sports Illustrated Swimsuit Issue cover model was lauded as the Model of the Year at the 10th annual Style Awards.

Fans can catch a tape of the awards show on CNN on Saturday, September 14 at 7/6 central.
