DiCaprio looked casual in jeans and a blue button down as he watched Serbia's Novak Djokovic play Britain's Andy Murray in Arthur Ashe Stadium. The 39-year-old actor donned his signature newsboy cap and kept his long hair in a ponytail for the event.
Djokovic beat Murray 7-6, 6-7, 6-2, 6-4 in Wednesday's match thus advancing to his eighth consecutive U.S. Open semi-final.
Like DiCaprio, many other celebrities have taken to the USTA Billie Jean King National Tennis Center over the course of the week to watch the 2014 U.S. Open. On Monday, fashionistas Mary-Kate Olsen and Heidi Klum were photographed simultaneously kissing their significant others, Olivier Sarkozy and Vito Schnabel, while watching Victoria Azarenka play Aleksandra Krunic in the fourth round of the tournament.
