Jimmy Fallon and Justin Timberlake danced at the U.S. Open to Beyonce. Watch the video here.

The U.S. Open has seen celebrity spectators from Donald Trump to Vanessa Williams this month, and Wednesday night the trend continued with two of today’s greatest celebrities: Jimmy Fallon and Justin Timberlake.

As Roger Federer took on Richard Gasquet in a men’s quarterfinal, the ESPN camera panned out to check on the crowd. As it honed in on Fallon and Timberlake, broadcaster Chris Fowler tried to dive into the highlights of the match... but made a pretty smooth segue into acknowledging the comedians.

“That was a good laugh for sure. These guys are on the money,” quipped John McEnroe, not sounding quite as entertained as Fowler. “They’d make a good doubles team.”
