Ivo Karlovic may have some slick skills on the court, but nothing comes close to these dance moves. During the Davis Cup, his daughter Jada Valentina busted out some impressive footwork as she watched her dad play for Croatia against Argentina's Juan Martin Del Porto.

Karlovic lost to Del Portro in the first singles rubber on Saturday and then went on to lose against Federico Delbonis in Sunday's decider, giving Argentina the Davis Cup title.

Despite the disappointment, the 37-year-old made history as the oldest player to compete in a Davis Cup final singles match in over a century.
