Celebrities came out of the woodwork over the weekend to support the top tennis players at the U.S. Open.
Justin Timberlake sat in the same stands on Saturday as Ben Stiller and his wife Christine Taylor, along with Michael Douglas and Catherine Zeta Jones, to observe the Men's semi-final match-up between Roger Federer and Novak Djokovic.
Djokovic remained the number one seeded tennis player after beating Federer and is set to play number two seed Rafael Nadal for the final Grand Slam title of the year today.
We're sure more celebs than ever will come out for that match too, but check out more pics from Saturday's event while eagerly awaiting the final match at the U.S. Open!
