Stars everywhere.

Rafael Nadal and Novak Djokovic might have been the stars on the court during the U.S. Open men's final in New York, but they weren't the only superstars on Monday.

From Hollywood actors like Leonardo DiCaprio and Kevin Spacey to singer/songwriter Justin Timberlake, and fashion designer Ralph Lauren were present at Arthur Ashe Stadium to enjoy the main event of the last Grand Slam of the year.

Even European royalty came to Flushing Meadows as Queen Sophia came all over from Spain to support her fellow countryman Nadal.
